Every religion must answer one unavoidable question:
Who is Jesus?
Some believe He was merely a great teacher. Others see Him as a prophet, a revolutionary, or an example of selfless love. Many admire His moral teachings while denying His divine nature. Yet the answer Jesus Himself demanded was far more significant.
When He asked His disciples, “Who do you say that I am?” (Matthew 16:15), He was asking the question upon which every person’s eternity rests.
Christianity does not merely teach that Jesus was sent by God.
It teaches that Jesus is God the Son, the second Person of the Trinity, who took on human flesh without ceasing to be God. He is fully divine and fully human—two complete natures united forever in one Person.
This truth stands at the very heart of the Christian faith.
If Jesus is merely a man, then His death could never accomplish the salvation of the world.
If He is only God appearing to be human, then He never truly shared in our humanity or became our perfect representative.
The gospel requires both.
The eternal Son of God became truly man while remaining fully God.
John begins his Gospel with one of the clearest declarations in all of Scripture:
«“In the beginning was the Word, and the Word was with God, and the Word was God.” (John 1:1)»
John intentionally echoes the opening words of Genesis. Before creation existed, the Word already was. He did not come into existence at Bethlehem. He existed from all eternity with the Father and shared the very nature of God.
Only a few verses later John writes,
«“And the Word became flesh and dwelt among us.” (John 1:14)»
The eternal Son did not cease to be God. Rather, He added to Himself a true human nature. Without surrendering His deity, He entered His own creation, experienced hunger, weariness, sorrow, temptation, and suffering, yet remained completely without sin.
This is the miracle Christians celebrate at Christmas—not merely the birth of a child, but the incarnation of God the Son.
Throughout His earthly ministry Jesus demonstrated both His humanity and His deity.
He grew tired.
He wept.
He slept.
He prayed.
He experienced genuine human suffering.
Yet He also forgave sins, received worship, calmed the sea, raised the dead, exercised authority over demons, and accepted titles that belong to God alone.
Thomas confessed the risen Christ,
«“My Lord and my God!” (John 20:28)»
Jesus did not correct him.
Instead, He received that confession because it was true.
The New Testament consistently proclaims that Jesus is far more than a messenger from God.
He is Emmanuel—“God with us.”
To know Jesus is to know the Father.
To reject Jesus is to reject the One who sent Him.
Everything Christians believe about salvation depends upon who Jesus is.
For that reason, the identity of Christ is not a secondary doctrine. It is the foundation upon which the entire gospel rests.
The Deity of Jesus Christ
The New Testament leaves no room for the idea that Jesus was merely a good man or an extraordinary prophet. From its opening pages to its final chapter, it presents Jesus Christ as fully and eternally God.
John begins his Gospel by declaring,
«“In the beginning was the Word, and the Word was with God, and the Word was God.” (John 1:1)»
This statement contains two profound truths. The Son is distinct from the Father—He was with God. Yet He also shares the very nature of God—He was God. There is distinction of Persons without division of essence.
The deity of Christ is affirmed throughout the New Testament.
Thomas fell before the risen Lord and confessed,
«“My Lord and my God!” (John 20:28)»
Rather than correcting Thomas, Jesus received his worship. Throughout Scripture, faithful servants of God refused worship because it belongs to God alone. Jesus accepted it because He is worthy of it.
Paul likewise describes Christ as,
«“…our great God and Savior Jesus Christ.” (Titus 2:13)»
The author of Hebrews records the Father saying of the Son,
«“Your throne, O God, is forever and ever…” (Hebrews 1:8)»
These are not isolated verses. They reflect the consistent testimony of the New Testament that Jesus possesses the full nature of God.
His works also reveal His deity.
The Scriptures teach that all things were created through Him (John 1:3; Colossians 1:16). He upholds the universe by His powerful word (Hebrews 1:3). He forgives sins, exercises authority over creation, raises the dead, and will one day judge the living and the dead.
These are not the works of a created being.
They are the works of God Himself.
Jesus also claimed divine authority in ways His hearers clearly understood. He declared,
«“Before Abraham was, I am.” (John 8:58)»
By identifying Himself with the divine name revealed to Moses, Jesus made a claim His audience immediately recognized. They attempted to stone Him because they understood Him to be claiming equality with God.
Likewise, Jesus said,
«“I and the Father are one.” (John 10:30)»
He was not claiming that He and the Father were the same Person, but that they share one divine nature. Once again, His listeners understood the significance of His words and accused Him of blasphemy because He, “being a man, made himself God” (John 10:33).
The deity of Christ is essential to the gospel. Only God possesses the infinite worth necessary to accomplish redemption for sinners. If Jesus were merely another human being, His death could only satisfy the penalty for His own life. Because He is the eternal Son of God made flesh, His sacrifice is sufficient for all who place their faith in Him.
For this reason, Christians worship Jesus, pray in His name, trust Him for salvation, and confess Him as Lord. We do not honor Him simply as a great teacher among many. We confess Him as the eternal Son of God, worthy of the same glory, honor, and worship as the Father and the Holy Spirit.
To deny the deity of Christ is to deny the Christ revealed in Scripture. To confess His deity is to confess the very heart of the Christian faith.
The Humanity of Jesus Christ
Just as the Scriptures clearly teach that Jesus is fully God, they also teach with equal clarity that He became fully man.
This truth is essential to the gospel.
The eternal Son of God did not merely appear to be human, nor did He temporarily disguise Himself as a man. He truly entered our world, taking upon Himself a real human nature while remaining fully God. From the moment of His conception by the Holy Spirit and His birth to the virgin Mary, Jesus possessed everything necessary to genuine humanity except sin.
John writes,
«“And the Word became flesh and dwelt among us.” (John 1:14)»
The incarnation was not the Son setting aside His deity. Rather, He added humanity to Himself. One Person now possessed two complete natures—fully divine and fully human—without confusion, without change, without division, and without separation.
Throughout the Gospels we see unmistakable evidence of Christ’s humanity.
He was born as an infant.
He grew in wisdom and stature (Luke 2:52).
He experienced hunger after fasting in the wilderness.
He became thirsty while hanging upon the cross.
He grew weary from long journeys and slept in the stern of a boat during a storm.
He rejoiced with friends, wept at the tomb of Lazarus, felt compassion for the crowds, and experienced deep sorrow in the Garden of Gethsemane.
The author of Hebrews reminds us that Jesus was,
«“…tempted in every respect as we are, yet without sin.” (Hebrews 4:15)»
This does not mean He merely understood temptation from a distance. He experienced the full reality of life in a fallen world, enduring weakness, suffering, rejection, and grief. Yet where Adam failed, where Israel failed, and where every one of us has failed, Christ remained perfectly obedient.
His humanity was necessary for our salvation.
Humanity had sinned.
Therefore humanity’s debt had to be paid.
Jesus became our representative, living the perfect life we failed to live and willingly offering Himself as the perfect sacrifice for our sins. As Paul writes,
«“For there is one God, and there is one mediator between God and men, the man Christ Jesus.” (1 Timothy 2:5)»
Because He is truly man, He is able to stand in our place.
Because He is truly God, His sacrifice possesses infinite worth.
The resurrection also confirms Christ’s continuing humanity. Jesus did not abandon His human body after rising from the dead. He invited His disciples to touch His hands and His side. He ate with them. He spoke with them. He ascended bodily into heaven, where He now reigns at the Father’s right hand as our great High Priest and Advocate.
Even today, Jesus remains fully God and fully man.
This truth gives believers tremendous comfort. Our Savior is not distant from our struggles. He knows what it is to suffer. He understands weakness. He has experienced grief, betrayal, pain, and temptation. Yet because He overcame sin and death, He is able to sympathize with our weaknesses and provide mercy and grace in our time of need.
The incarnation is therefore not merely a doctrine to be admired. It is the foundation of our hope. In Jesus Christ, God truly came near. He entered our broken world, bore our sins, conquered death, and now lives forever as the perfect Savior of all who place their faith in Him.
The Work of Jesus Christ
Jesus did not come into the world merely to teach, perform miracles, or provide an example of moral living. He came to accomplish what no one else could accomplish—the redemption of sinners.
From the very beginning of His earthly ministry, His mission was clear.
The angel announced to Joseph,
«“You shall call his name Jesus, for he will save his people from their sins.” (Matthew 1:21)»
Jesus Himself declared,
«“For the Son of Man came to seek and to save the lost.” (Luke 19:10)»
Humanity’s greatest problem has never been poverty, disease, political oppression, or ignorance. Those are all consequences of living in a fallen world, but they are not the root problem. Our greatest problem is sin. Every person has fallen short of God’s perfect standard and stands guilty before a holy God.
No amount of good works, religious devotion, or personal effort can erase that guilt.
For this reason, God sent His Son.
Jesus lived the life that Adam failed to live and the life that none of us have lived. Every thought, every word, and every action was perfectly obedient to the Father. He fulfilled the Law completely, becoming the spotless Lamb of God without blemish or defect.
His perfect obedience was followed by His willing sacrifice.
Jesus was not a victim of circumstances or merely the target of political injustice. He willingly laid down His life.
He declared,
«“No one takes it from me, but I lay it down of my own accord.” (John 10:18)»
Upon the cross, Christ bore the penalty our sins deserved. The justice of God against sin was satisfied as the mercy of God was extended to sinners. As Isaiah foretold centuries earlier,
«“He was pierced for our transgressions; he was crushed for our iniquities… and the LORD has laid on him the iniquity of us all.” (Isaiah 53:5–6)»
The apostle Paul explains,
«“For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.” (2 Corinthians 5:21)»
This is the heart of the gospel. Christ took our guilt upon Himself so that all who trust in Him might receive His righteousness.
His work did not end at the cross.
On the third day, Jesus rose bodily from the dead, conquering sin, death, and the grave forever. The resurrection is God’s public declaration that Christ’s sacrifice was accepted and that death no longer has dominion over Him. Because He lives, all who belong to Him have the sure hope of eternal life.
Forty days later, Christ ascended into heaven, where He now reigns at the Father’s right hand. He is our King, our Great High Priest, and our Advocate. Even now He intercedes for His people, and one day He will return in glory to judge the living and the dead, establish His everlasting kingdom, and make all things new.
Every aspect of Christ’s work points to God’s grace.
We did not earn our salvation.
We could not accomplish our own redemption.
From beginning to end, salvation is God’s work through His Son.
For this reason, Christians place their hope in Christ alone. We trust neither our own righteousness nor our own accomplishments. Our confidence rests entirely in the finished work of Jesus Christ, who lived for us, died for us, rose for us, and even now reigns for us until the day we see Him face to face.
Why the Person and Work of Christ Matter
The identity of Jesus Christ is not a secondary doctrine.
It is the very heart of the Christian faith.
Everything Christians believe about salvation depends upon who Jesus is and what He accomplished. If Jesus is not fully God, He cannot reveal the Father perfectly or provide a sacrifice of infinite worth. If He is not fully man, He cannot stand in our place as our representative or fulfill the obedience that humanity failed to render.
The gospel requires both.
Because Jesus is fully God and fully man, He alone is the perfect Mediator between God and mankind. He bridges the gap that sin created, not by ignoring God’s justice, but by satisfying it completely through His life, death, and resurrection.
This is why Scripture repeatedly declares that salvation is found in Christ alone.
Peter boldly proclaimed,
«“And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved.” (Acts 4:12)»
Jesus Himself said,
«“I am the way, and the truth, and the life. No one comes to the Father except through me.” (John 14:6)»
These are exclusive claims, but they are not arrogant claims. They are invitations from the only Savior who has conquered sin and death. Christians do not believe Jesus is one path among many because Jesus Himself never claimed to be one option among many. He claimed to be the only Savior God has provided for the world.
Because Christ’s work is complete, believers can have confidence in their salvation.
Our hope is not built upon our performance but upon His finished work. When Jesus cried from the cross,
«“It is finished.” (John 19:30)»
He declared that the work necessary to secure the salvation of His people had been accomplished. Nothing can be added to His perfect sacrifice, and nothing can improve upon His perfect righteousness.
This truth transforms the Christian life.
We obey Christ not to earn God’s acceptance but because we have already been accepted in Him.
We worship not out of fear that our efforts may never be enough, but out of gratitude for the grace we have freely received.
We serve others because Christ first served us.
We forgive because we have been forgiven.
We love because He first loved us.
Our entire lives become a response to the immeasurable mercy God has shown us through His Son.
For this reason, the Christian life is ultimately Christ-centered. We do not merely admire His teachings or seek to imitate His example. We trust Him as our Savior, submit to Him as our Lord, worship Him as our God, and eagerly await the day when faith becomes sight.
The more clearly we understand who Jesus is and what He has accomplished, the more we will love Him, worship Him, and proclaim Him to the world. For there is no greater message than the gospel, and there is no greater Savior than Jesus Christ, the eternal Son of God made flesh for our salvation.
Conclusion
The message of Christianity is not ultimately about a system of ethics, a set of religious practices, or even a collection of theological doctrines.
It is about a Person.
From Genesis to Revelation, the Scriptures point us to Jesus Christ—the eternal Son of God who entered His creation to accomplish the redemption that sinners could never accomplish for themselves.
He is the promised Seed who would crush the serpent.
He is the true Passover Lamb.
He is the greater Prophet like Moses.
He is the perfect High Priest.
He is the Son of David whose kingdom will never end.
He is the Good Shepherd, the Bread of Life, the Light of the World, the Resurrection and the Life, the Alpha and the Omega.
Every promise of God finds its fulfillment in Him.
Because of who He is, we have confidence that His sacrifice is sufficient.
Because of what He accomplished, we have peace with God.
Because He rose from the dead, we have the hope of everlasting life.
Because He reigns today, we know that nothing can separate His people from His love.
And because He has promised to return, we eagerly await the day when faith becomes sight and every knee bows before the King of kings and Lord of lords.
Our salvation does not rest upon our goodness, our religious performance, or our ability to earn God’s favor. It rests entirely upon the finished work of Jesus Christ. He has done what we could never do, paid what we could never pay, and secured what we could never obtain for ourselves.
For this reason, we gladly confess with the church throughout the ages that Jesus Christ is fully God and fully man, the only Savior of the world, the only Mediator between God and mankind, and the only hope for sinners.
To Him be all glory, honor, dominion, and praise forever.
«“Jesus Christ is the same yesterday and today and forever.” (Hebrews 13:8)»
