Is Jesus God? The Biblical Case for His Deity
Calling Jesus a great teacher can sound respectful, but it becomes a dismissal if we refuse what He taught about Himself. Scripture presents Him as the eternal Son who created all things, became truly human, and gave His life to save us. I cannot accept that description and then offer Him only the admiration I would give a gifted religious teacher. To understand the response He deserves, we need to consider His identity alongside His words and works.
The Only Saving Name and the Old Testament Promise
In Acts 4, Peter and John stood before Jerusalem’s religious authorities after the healing of a man lame from birth. The leaders demanded to know by what power or name they had acted. Peter identified Jesus Christ of Nazareth, whom those leaders had crucified and whom God had raised. He then declared that salvation could be found in Jesus alone:
Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved.
The Greek word onoma means “name,” but Peter was not giving them a sound to repeat as though it possessed magical power. A name identifies a person and can convey his authority and reputation. Peter was directing them to Jesus Himself. The leaders who had rejected Him needed to be saved through Him, just as everyone else did.
This verse tells us where salvation is found. To understand who this Savior is, we need the wider testimony of Scripture. Prophets and apostles faithfully direct people to God, and angels deliver His messages, but Jesus is not simply another messenger in that company. God gave His own Son in the flesh as the only Savior.
The Old Testament prepares us for a Messiah who would be a truly human descendant of David while bearing divine titles. The passages also promise that God Himself would come to save. Isaiah’s description of the coming King brings His humanity and divine identity together:
For unto us a Child is born, Unto us a Son is given; And the government will be upon His shoulder. And His name will be called Wonderful, Counselor, Mighty God, Everlasting Father, Prince of Peace.
“Mighty God” is far more than a compliment for a capable ruler. Isaiah uses that title for the LORD Himself, yet here gives it to the promised Child. I understand “Everlasting Father” in this royal setting as describing His enduring, fatherly care for His people. It does not make the Son the same Person as the Father; Scripture distinguishes them throughout.
Isaiah also told people who were afraid that their God would come to save them:
Say to those who are fearful-hearted, “Be strong, do not fear! Behold, your God will come with vengeance, With the recompense of God; He will come and save you.”
The following verses describe blind eyes opening, deaf ears hearing, and the lame walking. When the Gospels describe Jesus healing those afflictions, we should hear that earlier promise. His deliverance of people from demons and His authority to forgive sins also marked the arrival of God’s kingdom. In His Son, God drew near as the Savior He had promised.
Psalm 45 addresses a righteous King whose throne endures forever:
Your throne, O God, is forever and ever; A scepter of righteousness is the scepter of Your kingdom.
Paul quotes this Psalm in Hebrews, introducing the words as the Father’s address to the Son:
But to the Son He says: “Your throne, O God, is forever and ever; A scepter of righteousness is the scepter of Your kingdom.”
The Father addresses the Son as God. In a chapter contrasting Him with angels, Paul does not present Jesus as the most distinguished angel. The angels serve and worship, while the Son reigns on an everlasting throne. The Son’s deity is affirmed in these prophetic and apostolic passages, so it cannot be dismissed as an invention added after the apostles.
The Eternal Word and Jesus’ Own Claims
John begins his Gospel before Bethlehem, with the Word who already existed in the beginning:
In the beginning was the Word, and the Word was with God, and the Word was God.
The Word was with God, so He is personally distinct from the Father. The Word was also God, identifying His divine nature. John gives us no room to reduce Him to an exalted angel or a lesser god. Nor can we make Him another name for the Father without losing the relationship John describes. This eternal Word is the One who came among us:
And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth.
The Word’s existence did not begin when He became flesh. He took a complete human nature without surrendering His deity. We call this the incarnation: the eternal Son became truly human while remaining fully God. He can reveal the Father perfectly and, as a sinless man, stand in our place. His sacrifice has infinite worth because the One who offered Himself is the eternal Son.
Some people maintain that Jesus never claimed to be God. His statements need to be heard in their setting, including the Old Testament language familiar to His hearers. In John 8, the discussion concerned Abraham when Jesus said:
Jesus said to them, “Most assuredly, I say to you, before Abraham was, I AM.”
Jesus was claiming more than an earlier birth date. The Greek ego eimi means “I AM,” and I understand His declaration here as an echo of God’s self-identification. The words occur in a statement about His existence before Abraham, and His hearers responded by taking up stones.
A similar confrontation followed in John 10. Jesus had said that He gives His sheep eternal life and that no one can snatch them from His hand. He gave the same assurance about His Father’s hand before declaring:
I and My Father are one.
The Greek word translated “one” is the neuter hen. It expresses unity without saying that Jesus and the Father are the same Person; His references to Himself and His Father preserve their distinction. We cannot explain the passage through modalism, the view that one Person merely appears in different roles. Nor does this setting allow us to reduce His claim to the sort of agreement two ordinary people might have. His opponents understood that He was claiming something far greater:
The Jews answered Him, saying, “For a good work we do not stone You, but for blasphemy, and because You, being a Man, make Yourself God.”
Their accusation is not our only evidence. In His response, Jesus directed them to His works so they would recognize the Father in Him and Himself in the Father. He did not withdraw His claim and explain that He was merely a teacher who agreed with God. His own words and works must determine our understanding, rather than an isolated phrase detached from the exchange.
Divine Honor and Works That Belong to God
Angels and faithful human servants refuse worship because it belongs to God. Jesus received it. After His bodily resurrection, Thomas addressed Him with a confession that would have been blasphemous if spoken to a mere creature:
And Thomas answered and said to Him, “My Lord and my God!”
Jesus did not reprimand Thomas or suggest that gratitude had carried him too far. He accepted the confession. John then explains that he wrote so readers would believe Jesus is the Christ, the Son of God, and receive life in His name. Thomas’s recognition of the risen Lord belongs within that purpose. He was right to call Jesus Lord and God.
Jesus had also instructed people to give Him the same honor they gave the Father:
that all should honor the Son just as they honor the Father. He who does not honor the Son does not honor the Father who sent Him.
A prophet demanding divine honor would be usurping what belongs to God. Yet Jesus says that withholding honor from Him dishonors the Father who sent Him. I cannot claim to honor the Father while refusing to worship His Son as He truly is.
The works Scripture attributes to Jesus agree with that honor. Paul identifies Him as the Creator and sustainer of everything that has been made:
For by Him all things were created that are in heaven and that are on earth, visible and invisible… All things were created through Him and for Him. And He is before all things, and in Him all things consist.
Christ cannot be one of the things He created. They came into existence through Him and for Him, and their continued existence depends on Him. Saying that a godly man performed remarkable miracles does not explain how Jesus created and sustains the entire universe.
In Mark 2, Jesus’ forgiveness of a paralytic’s sins brought the question of His authority into the open. The scribes understood that forgiveness belongs to God. Jesus told them He would heal the man so they could know He possessed the authority they were disputing:
“But that you may know that the Son of Man has power on earth to forgive sins” — He said to the paralytic,
He then told the man to rise, take up his bed, and go home. The man did so in front of them. Jesus was exercising authority on earth to forgive sins, rather than merely telling the man where forgiveness might be available. In John 5, He also claims the right to give life according to His will, and the Father entrusts judgment to Him. He exercises these divine rights in perfect unity with the Father. The honor He receives fits the works He does and the identity He claims.
True Humanity and the Passages Used as Objections
None of this permits us to dismiss Jesus’ humanity. He was conceived by the Holy Spirit and born of the virgin Mary, as the study on The Virgin Birth examines further. He grew, experienced hunger, needed sleep, and wept. His suffering, death, and bodily resurrection were real. This human life belonged to the eternal Son, including the prayers Paul describes in Hebrews:
who, in the days of His flesh, when He had offered up prayers and supplications, with vehement cries and tears to Him who was able to save Him from death, and was heard because of His godly fear,
In praying to the Father, Jesus expressed the genuine dependence of the human life He had taken upon Himself. He was obeying the Father as a real man, not acting a part or speaking to Himself. His humanity and His personal distinction from the Father explain those prayers without requiring us to deny His deity.
John 14:28, where Jesus says His Father is greater than He is, must also be read in context. He was preparing the disciples for His departure and return to the Father. I understand His words to concern the humbled position He accepted in His earthly mission, rather than an inferior divine nature. The same Gospel calls the Word God, records His divine “I AM,” and presents Thomas addressing Him as God. We need to account for all of those statements when explaining His relationship to the Father.
Another objection comes from Paul’s description of Christ as firstborn:
He is the image of the invisible God, the firstborn over all creation.
Here firstborn describes His supreme rank and rightful inheritance. The next verse, which we have already read, explains why it cannot mean He was the first creature God made. All created things came through Him and exist for Him. Paul places Christ over creation as its Creator, not within it as its oldest member.
Scripture presents one Person with both a complete divine nature and a complete human nature: the God-man, personally distinct from the Father. If His humanity were merely an appearance, we would lose the real body and blood given for us. If He were merely human, we would lose the eternal Creator these passages reveal. We cannot remove either nature without changing the Christ we proclaim. A Complete Bible Study on the Trinity considers the distinctions between the Father, Son, and Holy Spirit.
A teacher may call Jesus “Son of God” while insisting that He is a creature or an angel. Those claims cannot be reconciled with His creation of all things or with Thomas’s confession. Scripture certainly calls Him a Prophet, but stopping there would leave much of its testimony about Him unexplained. We need to ask what a teacher actually means by the words he uses, rather than assume familiar terminology guarantees that he is teaching the biblical Christ.
The Cross Requires This Christ
The eternal Son became human and lived without sin so that He could give His life for us. His identity is essential to understanding what happened at the cross. Scripture identifies His blood as the means of our redemption:
in whom we have redemption through His blood, the forgiveness of sins.
Redemption means release through the payment of a price. Paul identifies that price as Christ’s blood, directing us to what He actually suffered in His body. Jesus willingly gave Himself to be slain as the perfect, sinless sacrifice for our sins. Wicked people inflicted His bodily torture and death. His offering was complete through His shed blood and death before His burial and bodily resurrection. The Father did not punish, curse, abandon, strike, bruise, or pour wrath on Jesus. Father and Son remained united in redemption.
For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him.
Bearing our sins did not make Jesus sinful. He remained the innocent substitute who gave Himself for us. His deity did not make His suffering unreal, and His humanity did not diminish His divine identity. He was buried and rose bodily, vindicating His completed work and giving living hope to those who trust Him. The risen Savior now lives to intercede for His people, representing them before the Father.
We can now return to Peter’s declaration in Acts 4:12. Salvation is found in this Jesus. He died for the whole world, and God’s offer is genuine even though people can resist and reject it. Everyone who repents and believes is forgiven and justified, meaning declared righteous before God. That person is born again. The Holy Spirit comes to live within him and seals him in Christ.
Every genuine believer is eternally secure, but assurance gives no permission for lawlessness. Calling myself a Christian does not establish that I have been born again. We should see evidence of the new life God gives, rather than assume that a profession alone proves someone has received that life. Soteriology: The Study of Salvation develops these truths more fully.
The Son’s coming should humble me. Better conduct or greater religious knowledge could not bring me up to God. He came to us and accomplished what we could not provide for ourselves. I can be confident because His shed blood and completed sacrifice have secured the acceptance I could not earn.
My Final Thoughts
I cannot read these passages and give Jesus only a flattering description as a teacher or moral example. The eternal Son who created all things became truly human, shed His blood, and died for us before rising bodily. Thomas rightly called Him “My Lord and my God.” That is the recognition my faith and worship should express. We can come to Him in repentance and faith, confident that the Savior Scripture reveals has both the authority and the ability to save.
