What Is the Gospel? The Good News of Jesus Christ
When I explain the gospel, I need to say more than that God wants to improve someone’s life. The good news concerns what Jesus Christ has done for sinners: He shed His blood and died for our sins, was buried, and rose bodily from the dead. God calls us to repent and believe in Him. A person can agree that Christianity sounds beneficial without understanding why he needs that Savior.
The Greek word euangelion, translated gospel, means good news or a glad announcement. The message begins with God’s initiative in sending His Son. It calls for repentance and faith because He has provided a Savior, rather than promising to save us once we prove capable of improving ourselves.
If all I tell someone is that God has a wonderful plan for his life, I may encourage him while leaving his guilt unaddressed. He needs to hear why Christ shed His blood and rose from the dead, and what it means to repent and believe. We need to explain the judgment our sin deserves if he is to understand why forgiveness is good news.
The Bad News We Must Face
In Romans 3, Paul includes both Jews and Gentiles in the same verdict. Neither group can establish its righteousness before God, and the Jews’ religious privileges do not make their sin any less real:
for all have sinned and fall short of the glory of God.
The verb hamartano, translated sinned, can carry the sense of missing the mark. In Romans, the standard is God’s glory and righteousness, and the offense is our failure to give our Creator the obedience and worship we owe Him. The phrase cannot excuse disobedience as though we had merely made a harmless miscalculation.
If I have deceived someone, pointing to a more dishonest man does nothing to remove my guilt. A decent reputation cannot make the deception honest, and years of religious activity cannot undo it. The person whose sins are concealed needs forgiveness just as much as the person whose wrongdoing has become public.
Jesus confronted this self-righteousness after calling Matthew from the tax office. He shared a meal with tax collectors and sinners, and the Pharisees questioned His disciples about the company He kept. Jesus answered by explaining a physician’s purpose:
Those who are well have no need of a physician, but those who are sick. For I did not come to call the righteous, but sinners, to repentance.
Jesus was not telling the Pharisees they were righteous enough to do without a Savior. They objected to the mercy He showed people they regarded as sinners while failing to acknowledge their own need for it. If I insist that I am already well, I will not recognize my own need for the Physician.
Isaiah had exposed a similar refusal to face sin in Judah. The people needed God’s saving intervention, but the Lord had not lost the ability to save or hear. Their violence and injustice had separated them from Him.
But your iniquities have separated you from your God; And your sins have hidden His face from you.
Sin leaves us guilty before the holy God and breaks fellowship with Him. Becoming more disciplined cannot erase what we have done. Even making amends with someone we harmed does not, by itself, reconcile us to the Lord. We need Him to deal with our guilt and bring us back to Himself.
Paul develops the consequences of sin in Romans 6, where he contrasts slavery to sin with the freedom believers receive in Christ. He concludes by describing what sin pays and what God gives:
For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.
Paul calls death the wages of sin because it is a consequence our wrongdoing deserves, while eternal life is God’s gift in Jesus Christ to people who cannot earn it. Scripture speaks of physical death and the spiritual separation caused by sin, and it also warns of final judgment. The unredeemed dead will be raised and judged before being cast into the lake of fire, called the second death. I understand that as the final, irreversible destruction of body and soul. The gospel offers rescue from a real judgment, rather than reassurance that God will overlook our guilt.
Promised From the Beginning
God began promising that rescue long before the New Testament. Genesis 3 records Eve being deceived by the serpent and Adam knowingly disobeying God. Both sinned, and they hid from Him after becoming conscious of their shame. While pronouncing judgment on the serpent, God announced that the woman’s Seed would be wounded but would crush the serpent’s head.
And I will put enmity Between you and the woman, And between your seed and her Seed; He shall bruise your head, And you shall bruise His heel.
This promise points to the Deliverer who would defeat Satan, although it does not yet disclose everything later Scripture reveals about Christ. God was already announcing the rescue sinners needed. Through His covenants and the priesthood, He would teach His people more about that salvation. The prophets would also speak of the coming King’s suffering before victory.
Abraham also helps us understand how people receive what God promises. In Genesis 15, Abram was still childless despite the promise that he would become a great nation. God pointed him to the stars and promised descendants beyond counting.
And he believed in the LORD, and He accounted it to him for righteousness.
God accounted righteousness to Abram because he believed the Lord. He had not manufactured a righteousness of his own or made God indebted to him. Old Testament believers trusted the God who promised to save, although they did not know every detail of the cross and empty tomb. They were saved by grace through faith on the basis of the Redeemer He would provide. Teaching that they earned salvation by works while we receive it freely would misrepresent both their need and God’s provision.
God later instructed Israel about sin and approaching Him through the sacrifices He appointed under the Law. Sin and guilt offerings addressed wrongdoing. Peace offerings emphasized fellowship and could be given in thanksgiving, while the burnt offering expressed complete dedication and also made atonement. Their purposes differed, but blood was central to sacrificial atonement. In Leviticus 17, God explained that He had given blood on the altar and therefore prohibited eating it.
For the life of the flesh is in the blood, and I have given it to you upon the altar to make atonement for your souls.
God provided atonement, a way of dealing with sin so His people could approach Him. Yet Israel’s offerings could not provide the final cleansing the worshipers needed. Their repetition showed that something more was required, as Paul explains in Hebrews:
For the law, having a shadow of the good things to come, and not the very image of the things, can never with these same sacrifices make those who approach perfect.
The high priest returned to the Day of Atonement service year after year because the final offering had not yet been made. Christ was the perfect, sinless sacrifice those offerings anticipated, and He voluntarily gave Himself to be slain for our sins. Wicked men betrayed, mocked, beat, and crucified Him. The blood He shed and the life He gave accomplished the redemption those earlier sacrifices could not provide.
Paul calls God’s act of declaring the believer righteous justification. That standing is given freely through Christ’s redemption, the deliverance He secured at the cost of His life:
being justified freely by His grace through the redemption that is in Christ Jesus, whom God set forth as a propitiation by His blood, through faith.
Propitiation concerns the atoning provision through which God righteously grants mercy to sinners. Paul identifies Christ’s shed blood as that provision, received through faith. In the rest of his explanation, God remains just while justifying the person who has faith in Jesus. He forgives through the sacrifice He provided, rather than by dismissing our guilt.
The Father did not punish His innocent Son, abandon Him, or pour wrath upon Him. Father and Son acted in unity to provide our salvation. Jesus willingly endured the suffering wicked people inflicted as He gave His blood and life for us. Reducing the cross to an inspiring example would leave out the sacrifice through which God has provided mercy.
Christ the Fulfillment
The promised Redeemer is God’s eternal Son. In Galatians 3-4, Paul compares the Law’s temporary authority with a child’s life under guardians. The child is an heir, but he remains under their care until the time his father appoints. Paul then describes God sending His Son at the appointed time to redeem those under the Law and receive them as His children:
But when the fullness of the time had come, God sent forth His Son, born of a woman, born under the law, to redeem those who were under the law.
Jesus became fully man without ceasing to be fully God. He was born of a virgin and lived without sin, revealing the Father and perfectly obeying Him. God did not lower His standard to accommodate our wrongdoing. His Son willingly offered His sinless body and blood for the sins of the whole world.
Hebrews contrasts the priests who continued offering sacrifices with Christ’s completed offering. Paul describes believers as sanctified, or set apart, through the offering of His body:
By that will we have been sanctified through the offering of the body of Jesus Christ once for all.
His shed blood and death completed the atonement before His burial and bodily resurrection. The following verses in Hebrews contrast priests standing to offer sacrifices repeatedly with Christ seated after His one sacrifice. No priest can repeat that accomplishment or supply something it lacked. My suffering cannot complete it either, and law-keeping or a religious ritual cannot make me worthy of what He has done. Treating human merit as part of the basis for acceptance with God is legalism, and it contradicts the completeness of Christ’s offering.
That completed atonement does not make Christ’s resurrection optional. When some in Corinth denied the future resurrection of the dead, Paul answered by reminding them that Christ’s resurrection belonged to the gospel they had received:
For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures, and that He was buried, and that He rose again the third day according to the Scriptures.
Jesus truly died and was buried, then rose bodily on the third day. Paul goes on to name people who saw Him, including more than five hundred at once. He was making claims about events and witnesses, not describing how the disciples kept their teacher’s ideals alive.
In the same chapter, Paul says that if Christ has not risen, our faith is futile and we remain in our sins. His resurrection vindicates who He is and confirms the saving work He completed through His blood and death.
Paul also connects the resurrection with our justification in Romans 4:
who was delivered up because of our offenses, and was raised because of our justification.
Romans 4 applies Abraham’s example of faith to those who believe in the God who raised Jesus from the dead. We trust a living Savior who conquered death. Many people died on Roman crosses, but the gospel announces that the sinless Son died for our sins, fulfilling Scripture, and rose again. He is our only Savior and Mediator, the One through whom we come to God.
Repentance and Faith
Jesus Himself called people to repent and believe. Early in His ministry, after John the Baptist’s imprisonment, He began preaching in Galilee:
The time is fulfilled, and the kingdom of God is at hand. Repent, and believe in the gospel.
Years later, Paul described the same response while speaking to the Ephesian elders at Miletus. Looking back over his public and house-to-house ministry, he summarized what he had preached to Jews and Greeks:
testifying to Jews, and also to Greeks, repentance toward God and faith toward our Lord Jesus Christ.
Repentance turns a person from rebellion toward God, and faith trusts Jesus Christ as the only Savior. I cannot honestly claim to trust Him while insisting that He has no authority over my life. But turning to Him does not give me something to offer as payment. Neither my repentance nor the strength of my decision accomplishes the salvation He alone provides.
God’s invitation extends to every hearer. Jesus spoke of God’s love for the world and promised everlasting life to whoever believes in Him:
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.
Christ died for the whole world, so I can offer the gospel honestly to every person. I do not have to wonder whether the sinner in front of me is someone for whom no Savior was provided. People can resist and reject God’s genuine offer, and those who reject Christ remain condemned. Their unbelief cannot be blamed on Him withholding a genuine opportunity to respond.
Receiving His offer does not make salvation a human achievement. Ephesians 2 describes people dead in trespasses and sins, following the world and living according to corrupted desires. God makes believers alive with Christ because He is rich in mercy.
For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast.
Grace gives what we have not earned, and faith receives Christ and relies on Him. I cannot point to my religious background or my decision and claim that I made myself worthy of forgiveness. God has provided the Savior and gives the new life. Paul then explains the place of good works in the lives of those He saves:
For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.
When someone is genuinely born again, God gives him new life that should become evident in his conduct. A man who has been dishonest ought to learn to tell the truth and stop defending his deceit, although he will still need instruction and correction. Those changes are evidence of salvation already received; they are not a means of paying for forgiveness.
The claim that grace frees us from obeying God’s moral commands is called antinomianism. If I mistreat another person and insist that grace means God is unconcerned about it, I am turning His mercy into an excuse for disobedience. Christ saves people from slavery to sin and gives them a new life in which to follow Him.
Paul condemned the teaching pressed on the Galatian churches when Gentile believers were told they needed circumcision and law observance to be accepted by God. Making those observances necessary alongside Christ’s work changed the basis of salvation. That is why he treated the message as another gospel, rather than a cultural preference:
But even if we, or an angel from heaven, preach any other gospel to you than what we have preached to you, let him be accursed.
A message can also corrupt the gospel by changing Christ’s identity or setting aside His finished work. Prosperity teaching holds out earthly gain as the reason to come to Him, while a merely therapeutic message may offer comfort without confronting sin. Universalism promises that everyone will eventually be saved, removing the final danger Scripture attaches to rejecting Christ. Whatever encouragement, wealth, or improved behavior a message offers, it cannot substitute for the forgiveness sinners need through Him.
I reject Calvinist limited atonement because I believe Christ died for the whole world. The disagreement concerns the intended extent of His atoning death, rather than whether His blood has infinite worth. I do not believe salvation was provided only for the elect; God’s offer is sincere to every person. I also reject the Arminian teaching that genuinely born-again believers can lose salvation. People can resist God’s appeal, but those who repent and believe are made new and kept by Him.
When assessing a message, I need to consider more than whether the speaker sounds compassionate, morally serious, or impressive. A large crowd and a claim of spiritual power cannot establish that he is teaching the truth. I need to compare his explanation with the apostolic gospel preserved in Scripture: the truth about our sin, Christ’s full deity and humanity, His shed blood and bodily resurrection, and the call to repentance and faith. Salvation must remain God’s gift of grace that brings a person into new life.
For those who believe that gospel, assurance rests on Christ. In Ephesians 1, Paul praises God for the blessings believers have in Him and describes their hearing the gospel, trusting Christ, and being sealed by the Holy Spirit:
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.
Jesus also promised security to His sheep. During the Feast of Dedication, opponents surrounded Him in the temple and demanded that He tell them plainly whether He was the Christ. He told them they were not His sheep, then described those who heard His voice and followed Him.
And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand.
In the whole passage, their safety is in His hand and the Father’s hand. He gives them eternal life and promises they will never perish. The Holy Spirit lives in those genuinely born again and seals them as God’s own. Their obedience neither earns nor keeps salvation, because Christ is the One who keeps them. They may stumble and need to confess sin, but their weakness does not make His promise fail.
That promise should never be used to excuse a superficial claim without regeneration, which means genuine new birth. Baptism, church attendance, or repeating a prayer cannot take the Savior’s place. Neither can a Christian upbringing or a decent reputation. If I am relying on those things instead of Christ, I need to turn to Him. If I am trusting Him and grieving my weakness, I have reason to take heart in His promise as I learn to follow Him.
My Final Thoughts
I want someone hearing the gospel to understand both his guilt and the mercy God has provided. Jesus Christ died for our sins, was buried, and rose bodily from the dead. His blood is sufficient for the whole world, and He receives those who repent and believe. I cannot earn that forgiveness or complete His sacrifice, but I can trust the living Savior who makes His people new and keeps them forever.
