Jesus told Nicodemus, “You must be born again.” This man knew Scripture and held a respected position among Israel’s teachers, yet Jesus said he could not see God’s kingdom without new life from God. I need to hear that warning without assuming that knowledge, religious discipline, or a Christian background answers it. Jesus explains both who gives this life and how sinners receive it through faith in Him.
Why Nicodemus Needed More Than Religion
John 2 ends with people believing in Jesus’ Name because they saw His signs. Jesus did not entrust Himself to them, because He knew what was in man. John then introduces Nicodemus, a Pharisee and ruler of the Jews who came by night and acknowledged Jesus as a teacher sent from God.
His approach was respectful, but Jesus addressed more than his assessment of the miracles. Recognizing that God was with Jesus did not mean Nicodemus understood his own need or who Jesus fully was. The answer brought that need directly before him.
Jesus answered and said to him, “Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.”
John 3:3
Jewish ancestry, a place among Israel’s teachers, and Pharisaic discipline could not provide a substitute for this birth. Jesus did not tell Nicodemus to improve his standing or add another religious achievement. He needed life that only God could give.
Coming from a Christian family, attending church, learning Scripture, or serving in ministry cannot create that life either. Nor can an intense emotional experience. Those things may accompany a person’s conversion, but none has the power to make a sinner spiritually alive. When I speak of someone being born again, I mean that he has actually received new life through the Holy Spirit, not simply adopted the Christian name or become more interested in religion.
God’s work does not make our response irrelevant. Jesus went on to call Nicodemus to believe in the Son. The gospel presents a genuine appeal that a person can receive or resist, and he is responsible for that response. Believing does not produce life by human power; God gives life through His Spirit as the gospel is believed. Soteriology: The Study of Salvation considers this within the wider doctrine of salvation.
Born From Above by Water and the Spirit
Nicodemus took Jesus’ words as another physical birth and asked how an old man could enter his mother’s womb a second time. The Greek wording gennēthē anōthen can mean born again or born from above. Nicodemus was thinking about repeating natural birth, while Jesus was explaining life whose source is God.
Jesus continued by identifying the kind of birth required for entrance into the kingdom.
Jesus answered, “Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.”
John 3:5
That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.
John 3:6
Flesh can produce only flesh. Natural birth brings us into a human family, but it cannot bring us into God’s kingdom. A person also cannot create spiritual life within himself through determination. Yet Jesus’ birth analogy does not cancel His call to believe. He identifies the Spirit as the giver of life and directs Nicodemus to the Son in whom he must trust.
Some readers understand the water in John 3:5 as physical birth followed by spiritual birth. Others connect it with baptism. I believe the strongest background is God’s promise of cleansing and inward renewal in Ezekiel 36. God had promised to cleanse His people, give them a new heart and a new human spirit, and put His own Spirit within them.
Then I will sprinkle clean water on you, and you shall be clean; I will cleanse you from all your filthiness and from all your idols. I will give you a new heart and put a new spirit within you.
Ezekiel 36:25-26
Deuteronomy 30:6 likewise promises that God will circumcise His people’s hearts so they will love Him. These passages explain why Jesus could ask Nicodemus, “Are you the teacher of Israel, and do not know these things?” (John 3:10). As a teacher, he should have recognized God’s promise to change His people inwardly. Jesus was explaining a need that the law and prophets had already exposed.
I do not understand John 3:5 to make water baptism the cause of regeneration, the new birth. Baptism is Christ’s command for the believer after salvation, publicly identifying him with the Lord. It displays cleansing and union with Christ, but the outward act cannot produce the new heart that only God gives. We should obey the command without assigning the water the Spirit’s power to give life. Baptism in the Bible develops that distinction from the other baptism passages.
Faith in Christ and God’s Work of Regeneration
Jesus directed Nicodemus to a specific provision God had made in Israel’s wilderness years. In Numbers 21, the people sinned and were judged through fiery serpents. God instructed Moses to lift up a bronze serpent, and a person who had been bitten could look at it and live. The remedy came from God; the dying Israelites were called to respond to His promise.
And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up, that whoever believes in Him should not perish but have eternal life.
John 3:14-15
For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.
John 3:16
The lifted Son is the Savior God provides for the world. Faith trusts Him rather than presenting religious achievements as payment for life. Its value lies in the One trusted, so salvation is not a reward for managing to feel enough confidence. John’s opening chapter holds that response together with God’s work of giving new birth.
But as many as received Him, to them He gave the right to become children of God, to those who believe in His name: who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
John 1:12-13
People receive Christ and believe in His Name, while God gives them the right to become His children and brings about their birth. Bloodline and human power cannot accomplish it. I do not have to choose between God giving life and sinners needing to believe when John teaches both. Christ died for the whole world, and everyone who believes in Him receives the life He promises.
Paul uses palingenesia in Titus 3 for regeneration, meaning new birth or a new beginning. The sentence explains who accomplishes it and rules out our righteous deeds as its cause.
not by works of righteousness which we have done, but according to His mercy He saved us, through the washing of regeneration and renewing of the Holy Spirit.
Titus 3:5
Peter also identifies the means God uses to bring this life.
having been born again, not of corruptible seed but incorruptible, through the word of God which lives and abides forever.
1 Peter 1:23
The Spirit works through the living Word, so the gospel’s message cannot be replaced with vague spiritual advice. Jesus Christ is the eternal Son, fully God and fully man, born of a virgin and entirely sinless. Wicked men tortured, punished, and crucified Him. He willingly bore that real punishment for our sins in His innocent body, shed His blood, and died, completing His saving sacrifice. He was buried and rose bodily. The Father did not punish, curse, abandon, strike, bruise, or pour wrath on Jesus. Father and Son were united in this saving work. The Gospel develops Christ’s death and resurrection more fully, and The Blood of Christ for Salvation examines His shed blood in redemption.
As sinners believe this gospel and come to Christ, the Spirit gives them life. No believer can claim to have made himself alive, and no sinner is told to repair himself until he becomes worthy. God calls us to repent and believe. Repentance means turning to God instead of defending our sin, while faith rests on Jesus as Lord and Savior. Neither response buys salvation; we receive the grace He offers. The study on Repentance explains that turning to God more fully.
The Spirit’s Seal and the Believer’s Living Hope
Does someone born again have the Holy Spirit immediately, or must he wait for a further stage before belonging fully to Christ? Paul gives a direct answer.
Now if anyone does not have the Spirit of Christ, he is not His.
Romans 8:9
Everyone who belongs to Christ has His Spirit. The Spirit who gives life also indwells the believer, meaning He lives within him, and seals him as God’s own. Paul tells the Ephesians how this happened to them.
In Him you also trusted, after you heard the word of truth, the gospel of your salvation; in whom also, having believed, you were sealed with the Holy Spirit of promise.
Ephesians 1:13
They heard the gospel, trusted Christ, and were sealed with the Holy Spirit. Paul goes on to call Him the guarantee of their inheritance until the redemption of God’s purchased possession. My assurance rests on that promise, not on maintaining a particular feeling. The God who gave new life marks His children as His own and keeps them.
Indwelling is different from being filled with the Spirit for service or walking in obedience to Him. Believers are commanded to be filled and to walk by the Spirit. Sin grieves Him, and His conviction should move us to confession and repentance. It does not mean a truly born-again believer loses the seal and needs to receive it again each time he sins. His indwelling belongs to salvation itself.
David prayed, “Do not take Your Holy Spirit from me” (Psalm 51:11), and Saul lost the Spirit’s empowering presence associated with his kingship. Those passages warn us against presuming on God’s empowerment for an office. Their setting must also be distinguished from the New Covenant promise that every true believer is indwelt and sealed. They do not reverse the teaching of Romans 8 and Ephesians 1. The Holy Spirit Indwelling vs Coming Upon examines those different aspects of the Spirit’s work.
The life God gives also carries a future hope, grounded in the resurrection of Christ.
Blessed be the God and Father of our Lord Jesus Christ, who according to His abundant mercy has begotten us again to a living hope through the resurrection of Jesus Christ from the dead.
1 Peter 1:3
Peter was writing to believers facing suffering. Their hope rested on God’s mercy and the risen Christ, so their circumstances could not reduce it to wishful thinking. Jesus lives bodily, and those born of God share in a life whose future He secures. His completed sacrifice saves us, and His resurrection assures us that death will not have the final claim on His people.
God also brings us into His family now. New birth is more than a private experience that leaves us detached from other believers. We become His children and belong in the household of faith, learning to love and serve His people. The Spirit begins to produce His fruit in us because we have received life. That fruit is a result of salvation, never its purchase price.
Grace, Assurance, and the Fruit of New Life
Jesus’ warning to Nicodemus still prevents us from using religious standing as assurance. A Christian label is not the same as having received Christ. Someone who professes faith while persistently rejecting the Lord and showing no evidence of new life should not be reassured merely because he once used the right words. We need to ask whether we are trusting Christ rather than our membership, baptism, or service.
At the same time, new life does not mean sinless perfection. Believers struggle, stumble, need correction, and grow. We should encourage repentance and obedience without telling a troubled Christian that every failure cancels God’s saving work. Those truly born again are indwelt and sealed, and their new birth cannot be lost. God keeps His children; their religious intensity does not keep them alive.
For these reasons, I reject both Calvinism’s restriction of saving grace and Arminian loss-of-salvation teaching. Classical Calvinism, as expressed in the Canons of Dort, teaches that redemption is intended only for the elect, those God has chosen for salvation, and that His effectual call unfailingly brings them to faith. It also teaches that the gospel should be proclaimed to everyone and that its outward call can be resisted. I understand Scripture to teach that Christ died for all and that the grace offered to every person can be resisted.
God loved the world, and Christ gave Himself as a ransom for all. I cannot restrict that provision to a group selected apart from their response, nor treat faith as the sinner’s contribution toward the price of salvation. Everyone who believes in the Son receives life through God’s mercy. His invitation is genuine for every hearer, and receiving it gives no grounds for boasting.
I also reject the Arminian teaching that a person truly born again can finally fall away and lose salvation. That view takes the warnings against apostasy seriously, but I believe it makes the new birth and the Spirit’s seal reversible when Scripture presents them as God’s enduring work. Apostasy means abandoning the faith, and false profession is a real danger. Those warnings should expose empty claims and call people to Christ, while His promise gives assurance to everyone who truly belongs to Him.
Security in Christ gives us reason to turn from sin, not permission to settle into it. The Spirit grows love for God and for other Christians, and His children should increasingly show that life through obedience, confession, and repentance. Our assurance rests in Christ’s promise, while the evidence of His work should become visible in how we live.
When we call people to Christ, we must explain what He has done to save them. Advice about finding ourselves cannot give new birth. The Son of God shed His blood and died for sinners, then rose bodily, and He gives life to everyone who believes in Him. We should come to Him ourselves and direct others to Him without substituting religious activity for the life He gives.
My Final Thoughts
Nicodemus needed new life from God despite everything he knew and the position he held. We have the same need. The Holy Spirit gives that life as we receive Jesus Christ by faith, and He indwells and seals everyone truly born again. I want the certainty of His keeping to lead us toward repentance and obedience, with no attempt to earn what Christ gives freely. The invitation remains open: whoever believes in the Son has eternal life.
The indwelling of the Holy Spirit means that God’s Spirit lives in those who belong to Jesus Christ. That promise gives believers reason for assurance, but it also raises practical questions. If the Spirit lives in us, why do we still need to be filled with Him, and how should His presence affect our conduct? I want to follow what Scripture says about receiving Him, being sealed by Him, and learning to obey Him.
The Holy Spirit Is a Divine Person Who Dwells in Believers
We need to begin with who the Holy Spirit is. Scripture describes Him teaching, bearing witness, interceding, and distributing gifts according to His will. He can also be grieved. He is a divine Person who knows and acts, not an energy we generate or an atmosphere created during worship. The study on the Person of the Holy Spirit examines those passages more fully.
When Jesus prepared His disciples for His death and His return to the Father, He promised them “another Helper.” They would not have to continue their ministry without God’s presence and help.
“And I will pray the Father, and He will give you another Helper, that He may abide with you forever, the Spirit of truth, whom the world cannot receive.”
John 14:16-17
Jesus went on to say that the Spirit was with them and would be in them. The Spirit was already at work among these disciples, but Jesus was promising an abiding presence in them. His departure would not mean that God had abandoned them. The new-covenant life established through His saving work would include the Spirit making His home in His people.
The Greek word translated Helper is parakletos. It describes someone who gives aid and can carry the sense of an advocate or comforter, as Thayer’s Greek lexicon explains. Jesus specified the help the Spirit would give these men:
“But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you.”
John 14:26
This promise first concerned the disciples who had heard Jesus teach. The Spirit would bring His words to their remembrance and teach them, equipping them to bear faithful witness to Him. We should not turn it into a claim that every believer will know everything without study or that an inward impression can replace Christ’s words. The Helper teaches truth and directs attention to Christ.
That also affects how we speak about His power. If “using” the Spirit or “releasing” His power means that we can command Him to produce a result, we have misunderstood who He is. He acts with divine wisdom and holiness, giving gifts as He wills. We depend on His help and submit to His direction; He does not become an instrument for our ambitions.
Every True Believer Receives the Whole Spirit
Paul makes the relationship between belonging to Christ and having the Spirit quite plain:
“But you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. Now if anyone does not have the Spirit of Christ, he is not His.”
Romans 8:9
A person without the Spirit does not belong to Christ. We therefore should not tell a Christian that he is saved but must reach a higher spiritual level before the Spirit will live in him. Indwelling belongs to every true believer. A later experience of boldness, joy, or renewed obedience should not be treated as proof that the Spirit had been absent beforehand.
We receive the Spirit through faith in Christ, not by making ourselves impressive enough to deserve Him. Jesus, the sinless Son of God, became fully man without ceasing to be God. Wicked men inflicted His bodily suffering and death, but He willingly shed His blood and bore the punishment for our sins in His innocent body. His saving work was completed in His death before He was buried and rose bodily from the grave. Those who repent and trust Him are born again and receive the Spirit.
The related studies on being born again and soteriology, the study of salvation, explain that foundation. Religious effort cannot purchase the Spirit’s presence. His indwelling is part of the salvation God gives through Christ.
Because the Spirit is a Person, we do not receive Him in pieces. God does not give one believer a small percentage of Him and reserve the rest for more accomplished Christians. A believer may have much to learn and may resist the Spirit’s correction, but immaturity does not mean that he has received only part of the Spirit.
Ephesians 5:18 still commands believers to be filled with the Spirit. Acts 4:31 also records believers being filled again for witness and boldness. I need to ask whether I am yielding to the One who lives in me, rather than assuming that His presence makes further obedience unnecessary. The study on being filled with the Spirit develops that responsibility.
Sealed by the Spirit and Made God’s Temple
Paul connects receiving the Spirit with hearing the gospel and believing in Christ. He describes the Spirit Himself as God’s seal and the guarantee of the believer’s inheritance:
“In Him you also trusted, after you heard the word of truth, the gospel of your salvation; in whom also, having believed, you were sealed with the Holy Spirit of promise, who is the guarantee of our inheritance until the redemption of the purchased possession, to the praise of His glory.”
Ephesians 1:13-14
A seal identifies what belongs to its owner. Here, God marks believers as His own and gives His Spirit as the pledge that He will complete their redemption. The assurance rests on God’s action and promise. He has not left His people to secure their inheritance by maintaining a certain intensity of religious feeling.
This is one reason I believe Scripture teaches eternal security for everyone who has truly been born again. God seals His people for the redemption He has promised. Obedience does not earn that seal or keep it in force. We must distinguish genuine new birth from merely calling ourselves Christians, but we should not weaken God’s promise to those who really belong to Christ.
Paul himself brings the assurance and the warning together:
“And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption.”
Ephesians 4:30
These believers could grieve the very Spirit by whom they were sealed. His abiding presence did not make their conduct acceptable regardless of what they did. In the surrounding verses, Paul told them to put away bitterness, wrath, angry clamor, evil speaking, and malice, and to practice kindness and forgiveness. If I use the promise of security to excuse my refusal to forgive or my determination to keep sinning, I am disregarding the purpose for which Paul gave the warning.
Paul also describes God’s people as His temple. In the Old Testament, the tabernacle and temple were places associated with God’s presence among Israel. Now Paul tells the church that the Spirit dwells in them:
“Do you not know that you are the temple of God and that the Spirit of God dwells in you?”
1 Corinthians 3:16
In the context of 1 Corinthians 3, Paul is addressing the congregation together. Their envy and divisions were damaging a church that belonged to God. Calling them His temple gave them reason to take that conduct seriously. God’s presence among His people does not make them divine; it makes treating His church as a place for rivalry and self-promotion inexcusable.
In chapter 6, Paul applies temple language directly to the believer’s body while warning against sexual immorality:
“Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God, and you are not your own?”
1 Corinthians 6:19
The body cannot be treated as though it has nothing to do with our relationship to God. Paul reminds believers that they were bought at a price and must glorify God in their bodies. I cannot claim a private spiritual devotion that leaves my sexual conduct outside Christ’s authority. The Spirit’s indwelling gives comfort, but it also means that my life belongs to the Lord.
The Spirit Gives Life and Bears Witness to Sonship
The Spirit gives us new life in regeneration, the new birth. Jesus told Nicodemus that a person must be born of water and the Spirit. Paul likewise describes salvation as God’s merciful work of giving new life:
“Not by works of righteousness which we have done, but according to His mercy He saved us, through the washing of regeneration and renewing of the Holy Spirit.”
Titus 3:5
When I speak of regeneration, I mean someone has genuinely been born again. Adopting a Christian label or improving a few habits cannot produce that life. God saves and renews through His Spirit, and the new life should become evident in the person’s conduct. That evidence does not earn salvation, and it does not mean a new believer has already reached maturity.
Romans 8 and Galatians 4 also connect the Spirit with adoption, our being received as God’s children. Through Christ we belong to the Father, and the Spirit bears witness to that relationship:
“The Spirit Himself bears witness with our spirit that we are children of God.”
Romans 8:16
God does more than announce a status while leaving us strangers to Him. He sends the Spirit of His Son into our hearts, and we can approach Him as our Father. The Spirit does not draw our attention away from Jesus or make us independent of the Father. He assures us of the relationship God has given us through the Son.
I do not take this witness to mean that every strong feeling is God’s voice. The Spirit’s testimony agrees with the gospel and with the Word He inspired. A private impression cannot rightly assure someone who rejects Christ and refuses repentance that he is God’s child. A believer who trusts Christ, however, can rest in God’s promise without trying to produce a particular emotion to prove it.
Jesus used the image of living water to describe the life the Spirit gives:
“He who believes in Me, as the Scripture has said, out of his heart will flow rivers of living water.”
John 7:38
John immediately explained that Jesus was speaking of the Spirit whom believers would receive after Jesus was glorified. The source of this life is God, not a spirituality we manufacture. His Spirit renews us from within, and that life also benefits others as we serve and bear witness to Christ.
The Spirit helps us when we are weak. Romans 8 says that He intercedes when we do not know how to pray as we ought. He also produces the fruit of the Spirit and distributes the gifts of the Holy Spirit for the good of Christ’s body. His work includes both changing our character and enabling service. We depend on Him for a sanctified life, a life increasingly set apart to obey God.
Indwelling, Filling, Baptism, and Coming Upon Are Not Identical
These descriptions concern the same Holy Spirit and explain different aspects of His work. They can overlap, as when an indwelt believer is filled for service. Indwelling means that He lives in the believer. Sealing identifies us as God’s own and assures us of our inheritance. Being filled describes life under His active influence as we yield to Him, while coming upon often describes empowerment for a particular task, especially in the Old Testament and Acts.
Baptism by the Spirit speaks of His placing believers into Christ’s body. Paul emphasizes that this is shared by all believers, across differences of ancestry and social standing:
“For by one Spirit we were all baptized into one body, whether Jews or Greeks, whether slaves or free, and have all been made to drink into one Spirit.”
1 Corinthians 12:13
Acts records the promised Spirit being poured out at Pentecost, when the church’s public witness began in power. In Acts 4:31, believers prayed in the face of opposition and were filled for renewed boldness. The renewed filling did not mean that the Spirit had left these believers and needed to return. God was empowering people in whom His Spirit was already present. The study on the Holy Spirit indwelling versus coming upon follows those passages in more detail.
Confusing these works can produce needless fear. Someone who struggles with obedience may conclude that the Spirit has left him, while another person may think a dramatic experience proves his spiritual maturity. Neither conclusion follows. The believer needs to repent and grow, and a gifted person still needs humility, discernment, and obedience to Scripture.
I do not believe the gifts of the Spirit have ceased, but I also will not accept a spiritual claim simply because it is spectacular. Scripture must test what is being claimed. Gifts should serve love and truth and strengthen the church in an orderly way. A conspicuous ability does not give anyone permission to disregard Christ’s teaching or draw attention to himself at the church’s expense.
Living as the Spirit’s Dwelling Place
If you have repented and trusted Christ, you do not need to live as though God has left you spiritually abandoned. His promise is more dependable than the intensity of your latest experience. At the same time, assurance should deepen our reverence: the One dwelling in us is holy, and He has a rightful claim on our speech, our bodies, and the conduct no one else sees.
For me, yielding to Him needs to become specific. If I am nurturing bitterness, I need to forgive rather than keep rehearsing the offense as an excuse for malice. If I am entertaining impurity, I need to turn from it and ask for strength to obey. Calling myself indwelt by the Spirit does not settle the question of whether I am obeying what He has already made plain in Scripture.
We also have reason to pray when we cannot put our need into clear words. The Spirit’s intercession in Romans 8 is help for weakness, not a reward for praying impressively. I can come before the Father honestly, without pretending to understand everything that has happened or know exactly what to ask.
The Spirit glorifies Christ, so His work should increasingly turn our attention toward Jesus and make us willing to confess Him before others. We should want to serve His church and use what He gives for the good of fellow believers. Changed conduct, love, and faithful witness belong with the assurance of His presence; they are evidence of His work rather than a price we pay to retain Him.
My Final Thoughts
Every true believer receives the Holy Spirit and is sealed for the day of redemption. I want to trust that promise without making excuses for conduct that grieves Him. We belong to the Lord, and the Spirit who assures us of that relationship also gives life, helps us in weakness, and leads us in holiness. Our responsibility is to depend on Him, receive His correction, and obey the Word He inspired as He makes Christ known through our lives.
When I use the word regeneration, I am talking about someone who has genuinely been born again, not just someone who calls himself a Christian. A person can call himself a Christian, but we need to see evidence of the new creation through his actions. Jesus’ conversation with Nicodemus explains why even a respected religious teacher needed this change and how a sinner receives the life only God can give.
Nicodemus Needed New Life
John 2 ends with people believing in Jesus’ name because they had seen His signs. Yet Jesus did not entrust Himself to them, because He knew what was in man. In the next chapter, Nicodemus came to Him at night and acknowledged that His signs showed God was with Him. He was a Pharisee, a ruler of the Jews, and a recognized teacher of Israel. His respectful words and religious credentials did not remove the need Jesus addressed:
Jesus answered and said to him, “Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.”
John 3:3
Jesus’ word “unless” leaves no alternative entrance into the kingdom. Nicodemus could not obtain spiritual life through Jewish ancestry or a thorough knowledge of the Law. An admirable reputation could not give it to him either. He needed God to make him alive, because the problem went beneath what he knew and how other people regarded him.
Spiritual death means separation from God’s life and bondage to sin. It does not mean a sinner cannot hear and respond when God appeals to him. Jesus spoke to Nicodemus and went on to call him to believe. God’s Word and Spirit convict and draw people, who remain responsible to receive what He offers or resist His appeal. Responding in faith does not mean a sinner has somehow produced his own spiritual life.
Paul describes what God does for the person who comes to Christ:
Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new.
2 Corinthians 5:17
A new believer now belongs to Christ and has a relationship with God he did not have before. He still needs instruction and correction, so we should not expect him to know everything a mature believer knows. The new birth is a real beginning; maturity develops afterward. A man newly converted may still appear less polished than someone who has spent years around religion, while possessing the life that religious person still needs.
I cannot determine whether someone has been born again simply by how impressive he appears in church. Nicodemus already had learning and standing in his community when Jesus told him he needed new life. Growing up among Christians and learning to explain their beliefs can be valuable, but neither takes the place of personally receiving Christ.
Born Again Means Born From Above
Nicodemus took Jesus to mean a second physical birth and asked how an old man could enter his mother’s womb again. The Greek phrase gennethe anothen can mean “born again” or “born from above.” Jesus answered by explaining that the life Nicodemus needed must come from the Spirit:
Jesus answered, “Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.”
John 3:5
That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.
John 3:6
Natural birth gives us human life, but it cannot give us spiritual life. Jesus compared the Spirit’s work to the wind, whose sound we hear without being able to direct its course. We cannot manufacture the new birth either. The Spirit gives that life, and His work becomes evident in the person He makes alive.
Some understand “water and the Spirit” as physical birth followed by spiritual birth. The contrast between flesh and Spirit in verse 6 helps explain that reading. I find a fuller background in Ezekiel 36:25-27. God first promises cleansing from defilement and idols, then a new heart and a new human spirit, followed by His own Spirit dwelling within His people:
I will give you a new heart and put a new spirit within you; I will take the heart of stone out of your flesh and give you a heart of flesh. I will put My Spirit within you and cause you to walk in My statutes, and you will keep My judgments and do them.
Ezekiel 36:26-27
In John 3:10, Jesus rebuked Nicodemus for being Israel’s teacher and not understanding these things. God’s promise of cleansing and a changed heart was already in the Scriptures he taught. That is why I read “water and the Spirit” in light of Ezekiel’s promise.
I do not believe John 3:5 teaches that baptism produces regeneration. Baptism is a commanded act of obedience that publicly identifies a believer with Christ. It follows salvation rather than creating the new heart. An outward washing cannot replace faith in the Son or accomplish the Spirit’s work of making a sinner alive.
The New Birth Comes Through Faith in the Son
To explain how life comes through the Son, Jesus referred Nicodemus to Israel’s wilderness journey in Numbers 21. Israel had sinned against God, and venomous serpents brought death through the camp. God instructed Moses to raise a bronze serpent, and anyone who had been bitten could look at it and live. Jesus used that event to describe His own being lifted up:
And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up, that whoever believes in Him should not perish but have eternal life.
John 3:14-15
For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.
John 3:16
The Israelite who looked at the bronze serpent was not earning his recovery. God had provided the remedy and told him to look. In the same way, a sinner receives eternal life by believing in the Son. Faith doesn’t make him deserving of salvation or pay for any part of it. He is trusting the Savior to give what he could never obtain by improving himself.
I reject the Calvinist teaching of limited atonement, which says Christ’s saving death was only for the elect, those chosen for salvation. God loved the world and gave His Son so that whoever believes would not perish. His invitation is genuine for everyone, and Christ died for the whole world. People can resist God’s appeal and remain in unbelief, but everyone who believes in the Son receives eternal life.
Earlier, in the opening chapter of his Gospel, John describes the people who become God’s children:
But as many as received Him, to them He gave the right to become children of God, to those who believe in His name: who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
John 1:12-13
They receive Christ and believe in His name, yet the birth itself is God’s work. Christian parents can teach their children Scripture, but they cannot pass spiritual life to them through ancestry. Nor can anyone bring that life into existence through determination or decide another person’s conversion for him. Our response to the gospel is real, and God gives the right to become His children to those who receive His Son. Faith does not make that birth any less His work.
The Savior we trust is the eternal Son, fully God and fully man. He lived without sin and willingly gave Himself to be slain as the perfect sacrifice for our sins. Wicked men tortured and crucified Him, shedding His innocent blood and killing Him. The Father did not punish, curse, abandon, strike, bruise, or pour wrath on Jesus. Father and Son were united in saving sinners. Christ’s sacrifice was complete through His shed blood and death before He was buried and rose bodily from the dead. The Spirit gives life as a sinner believes this gospel, leaving us no grounds to boast. The study on the gospel examines His saving work further.
The Spirit Regenerates, Indwells, and Seals
Paul explains God’s saving work in Titus 3 by beginning with His mercy:
not by works of righteousness which we have done, but according to His mercy He saved us, through the washing of regeneration and renewing of the Holy Spirit.
Titus 3:5
The Greek word palingenesia means regeneration or new birth. Paul joins that beginning with the Spirit’s renewal as part of God’s saving act. He does not divide them into separate stages or make either a reward for good conduct. Here he is explaining how God saves, while other passages describe the continuing renewal that follows salvation. A person does not gradually earn enough maturity to become spiritually alive.
Peter connects this new birth with God’s living Word:
having been born again, not of corruptible seed but incorruptible, through the word of God which lives and abides forever.
1 Peter 1:23
The Spirit brings sinners to life through the truth of the crucified and risen Christ. A person need not have a dramatic conversion account to tell, but he does need the Savior revealed in the gospel. An intense private experience cannot replace that truth or become another way to receive life apart from Christ.
The Holy Spirit who gives this life is a divine Person. We may feel deeply moved in a church service, but that feeling is not the Spirit Himself. Jesus promised His disciples a Helper who would remain with them:
And I will pray the Father, and He will give you another Helper, that He may abide with you forever.
John 14:16
Paul makes clear that having the Spirit is part of belonging to Christ:
Now if anyone does not have the Spirit of Christ, he is not His.
Romans 8:9
Every person who truly belongs to Christ has the Spirit, including believers who are still immature. We do not keep ourselves spiritually alive by maintaining the emotional intensity of a particular service or experience. The Spirit lives within us, bears witness that we belong to God, and teaches us through His Word. He convicts us when we sin, even when we would prefer not to be corrected. The study on the Holy Spirit’s indwelling and coming upon explains His continuing presence more fully.
Paul also describes what God does for those who have believed the gospel:
In Him you also trusted, after you heard the word of truth, the gospel of your salvation; in whom also, having believed, you were sealed with the Holy Spirit of promise.
Ephesians 1:13
The order is hearing the gospel, believing in Christ, and being sealed with the promised Spirit. The seal marks God’s ownership and gives the believer security. In the next verse, Paul calls the Spirit the guarantee of our inheritance until the purchased possession is redeemed. Our future rests on God’s commitment to keep His people.
I therefore reject the Arminian teaching that someone genuinely born again can later lose that life. God keeps the people He has made alive. That assurance does not authorize me to rebel against Him. In Ephesians 4:30, Paul tells believers not to grieve the Spirit who sealed them for the day of redemption. In that same passage, he tells them to put away lying and to forgive one another. Being secure in Christ gives me no excuse to keep deceiving people or nursing a grudge against a fellow believer.
New Life Produces Living Fruit
Good works cannot cause regeneration, but the life God gives will not remain permanently fruitless. We should expect the Spirit’s presence to begin showing in a believer’s conduct. John gives us practical evidence of knowing Christ:
Now by this we know that we know Him, if we keep His commandments.
1 John 2:3
John had already warned against claiming to have no sin and instructed believers to confess their sins. He also identified Jesus as our Advocate, the One who acts on our behalf with the Father (1 John 1:8-2:6). John is not demanding sinless perfection. But a man cannot reasonably claim to know Christ while treating His commands as something he has no intention of obeying. New birth changes how we respond to the Lord, even while we still need correction and have much to learn.
We know that we have passed from death to life, because we love the brethren.
1 John 3:14
John explains this love in practical terms. If I see a fellow believer in need and have the means to help, love should move me to act rather than leave him with a few kind words (1 John 3:16-18). Being pleasant to people at church is not the whole of loving the brethren. The Spirit teaches us to care for people who belong to Christ, even when helping costs us time or money.
We should not demand instant maturity from a new believer. Old habits may still need to be confronted, and fear can hinder his growth. If a believer loses his temper, he needs to confess that sin and learn self-control. That does not mean he must be converted again every time he needs correction. His willingness to acknowledge the sin and receive instruction is part of learning to obey the Lord who saved him.
I should also be careful about reassuring someone who calls himself a Christian while remaining content to reject Christ’s commands. His label does not settle whether he has been born again. Obedience provides evidence of new life without purchasing it. John allows for struggle and confession, but he gives no reassurance to someone who intends to remain in unbelief and disobedience.
For the person who truly belongs to Christ, a difficult week does not undo the Spirit’s seal. We confess sin because it grieves the One who now lives within us, and we receive His correction without trying to earn our way back into life. Our assurance rests in the Savior and His promise to keep us, while His work begins to show in how we live.
My Final Thoughts
I cannot give myself the life Jesus said Nicodemus needed, and years around religion cannot supply it. God gives that life through His Spirit as a sinner believes in His Son. If you have not received Christ, His invitation is genuine: turn to Him in repentance and faith. If you belong to Him, you can trust His keeping power while learning to live as someone He has made new.
