Behold the Lamb - John 1:29
John 1:29 (NLT): “The next day John saw Jesus coming toward him and said, ‘Look! The Lamb of God who takes away the sin of the world!’”
Introduction: The Cry That Still Changes Lives
There are moments in Scripture that thunder across the centuries with such force that they still shake the soul today. John 1:29 is one of those moments.
John the Baptist stands there, the forerunner, the voice crying out in the wilderness, the man sent by God to prepare the way. Crowds have come. Religious leaders are watching. Expectations are rising. Israel is longing. The atmosphere is charged with anticipation.
And then John sees Jesus.
He does not say, “Behold the great teacher.”
He does not say, “Behold the miracle worker.”
He does not say, “Behold the moral example.”
He does not even say, “Behold the King,” though Jesus is King indeed.
He says, “Look! The Lamb of God who takes away the sin of the world!”
That is not merely a beautiful phrase. It is the very heart of the Gospel. It is the Spirit-inspired declaration of who Jesus is and why He came.
And in a confused, anxious, and broken twenty-first century world, people are still asking the deepest questions of the human soul:
How can guilt be removed?
How can shame be cleansed?
How can sin be dealt with?
How can a holy God receive sinful people?
How can anyone truly be saved?
John 1:29 answers it with breathtaking clarity:
Jesus is the Lamb of God.
He did not come merely to improve us. He came to save us.
He did not come merely to advise sinners. He came to bear their sin.
He did not come merely to inspire the world. He came to redeem it.
So today, let us gather around this glorious declaration and ask God to help us not merely to admire the Lamb, but to trust Him, follow Him, worship Him, and proclaim Him.
Reading of the Main Text
John 1:29 (NLT): “The next day John saw Jesus coming toward him and said, ‘Look! The Lamb of God who takes away the sin of the world!’”
This single verse is rich with truth. It reveals:
The call to behold Jesus
The identity of Jesus as the Lamb of God
The mission of Jesus to take away sin
The global scope of His saving work
Let us take each of those in turn.
1. Look to Jesus: The Call to Behold the Lamb
John says, “Look!”
Other translations render it, “Behold!” The Greek word carries the idea of seeing with attention, fixing the eyes upon, looking with understanding and faith. This is not a casual glance. This is a summons.
John is saying, in effect, “Stop looking everywhere else. Stop looking at me. Stop looking at religion. Stop looking at ritual. Stop looking at yourselves. Look to Him.”
That is discipleship at its beginning. Before we can follow Jesus, we must first behold Jesus. Before we can obey Him, we must know Him. Before we can live for Him, we must see Him as He truly is.
John the Baptist had a remarkable ministry, but he understood his role. Earlier in this chapter he makes clear that he himself is not the Messiah. He is only the witness. He is only the herald. He is only the voice. His whole ministry is one great finger pointing away from himself and toward Christ.
And that is what true ministry always does.
It does not create admiration for the preacher.
It does not create dependence on personality.
It does not entertain the flesh.
It points men and women to Jesus Christ.
In our age, people are looking everywhere. They are looking to self-help, success, technology, politics, relationships, pleasure, identity, spirituality without repentance, and religion without the cross. But none of those can remove sin. None of those can reconcile us to God. None of those can save the soul.
The first call of John 1:29 is simply this: Look to Jesus.
Isaiah 45:22 (NLT): “Let all the world look to me for salvation! For I am God; there is no other.”
Historically, Isaiah spoke into a world of idols, false trusts, and human pride. The Lord declares that salvation is found in Him alone. The Hebrew thought behind this looking is not a passing glance but a turning of trust.
How relevant that is today. Ours is also an age of idols. They may not be carved in wood and stone, but they are just as real. Career can be an idol. Comfort can be an idol. Approval can be an idol. Even ministry can become an idol if it takes the place of Christ Himself.
The call remains: “Look to me for salvation!”
And in the full light of the New Testament, we understand that the God who says, “Look to me,” has revealed His saving glory in His Son.
John Piper said, “Saving faith is the confidence that if you look away from yourself to Christ, He will not fail you.”
That is exactly right. Faith is not confidence in our grip on Christ, but confidence in Christ Himself.
Friends, the power of salvation does not lie in the strength of your trembling hand, but in the strength of the Saviour to whom that hand reaches.
Some of you today are exhausted because you have been looking inward for what can only be found upward. You have examined yourself, analysed yourself, blamed yourself, excused yourself, and hidden yourself. But salvation does not come by self-inspection. It comes by looking to Christ.
Disciple of Jesus, keep looking to Him.
Backslider, look again.
Seeker, look for the first time in saving faith.
Broken heart, look to the Lamb.
2. Know Who He Is: The Lamb of God
John does not merely say, “Look.” He tells us what to see: “The Lamb of God.”
This is one of the richest titles in all the Bible.
To John’s Jewish hearers, the word “lamb” would have carried deep echoes from the Old Testament. It would call to mind sacrifice, substitution, blood, atonement, innocence, and worship. This was not accidental language. It was loaded with redemptive meaning.
Jesus is called the Lamb of God because He is God’s appointed, God’s provided, and God’s accepted sacrifice for sin.
There are several Old Testament backgrounds to this title.
A. The Passover Lamb
Exodus 12:3, 5, 13
At Passover, each household was to take a lamb without defect. Its blood was applied to the doorposts. When judgment came upon Egypt, the Lord said that where He saw the blood, judgment would pass over.
This was not because the people inside were sinless. It was because a substitute had died.
The lamb was not merely an example. It was a sacrifice.
This points directly to Christ.
1 Corinthians 5:7 (NLT): “For Christ, our Passover Lamb, has been sacrificed for us.”
Paul explicitly identifies Jesus as the fulfilment of Passover. The Greek word used here for sacrifice carries the sense of an offering made up to God. Christ is not a tragic victim of circumstance. He is the willing sacrifice ordained in the eternal plan of God.
The blood on the doorposts in Exodus pointed forward to the blood on the cross.
The sheltered household pointed forward to the believer hidden in Christ.
The passing over of judgment pointed forward to justification by faith.
You are not saved because you are good enough.
You are not saved because you come from a Christian family.
You are not saved because you attend church.
You are saved only if you are under the blood of the Lamb.
That is why discipleship begins with redemption. You cannot follow Christ rightly until you have first been rescued by Christ savingly.
B. The Lamb Provided by God
Genesis 22:7–8, 13–14
On Mount Moriah, Isaac asked Abraham, “Where is the sheep for the burnt offering?” Abraham answered, “God will provide a sheep for the burnt offering, my son.”
And God did provide.
Historically, this passage takes place in the great testing of Abraham’s faith. Theologically, it is one of the clearest foreshadowings of substitution in all the Old Testament. The Hebrew idea in “provide” carries the sense not only of supplying, but of seeing to it.
God Himself sees the need, and God Himself provides the answer.
When John says, “The Lamb of God,” he is telling us that Jesus is not man’s attempt to reach God. Jesus is God’s provision for man’s deepest need.
Religion says, “Bring your best to God.”
The Gospel says, “God has given His best for you.”
Tim Keller said, “The Gospel is this: We are more sinful and flawed in ourselves than we ever dared believe, yet at the very same time we are more loved and accepted in Jesus Christ than we ever dared hope.”
That is the wonder of the Lamb of God. He meets us at the intersection of our deepest guilt and God’s deepest grace. He does not minimise sin, but neither does He leave the sinner without hope.
The modern world wants spirituality without sacrifice, forgiveness without repentance, and heaven without the cross. But there is no salvation apart from the Lamb. God has not provided many ways. He has provided one Saviour.
And that Saviour is enough.
C. The Suffering Servant Like a Lamb
Isaiah 53:5 (NLT): “But he was pierced for our rebellion, crushed for our sins. He was beaten so we could be whole. He was whipped so we could be healed.”
Isaiah 53:7 (NLT): “He was oppressed and treated harshly, yet he never said a word. He was led like a lamb to the slaughter…”
Historically, Isaiah 53 stands as the great prophetic portrait of the suffering Messiah. The Hebrew language is full of substitution. “For our rebellion.” “For our sins.” He suffers not for His own wrongdoing, but for ours.
The lamb here is not only gentle and innocent, but sacrificial and silent in willing submission.
When John the Baptist sees Jesus and declares Him to be the Lamb of God, he is saying that the promised suffering servant has arrived.
The One who would be pierced has come.
The One who would bear iniquity has come.
The One who would die in the place of sinners has come.
Do not make the mistake of thinking lightly of sin. If your sin could have been removed by moral reform, Christ need not have died. If your sin could have been cleansed by religious effort, Christ need not have shed His blood. The very fact that Jesus came as the Lamb of God tells us how serious sin is.
But it also tells us how great God’s love is.
3. Understand Why He Came: To Take Away Sin
John says, “The Lamb of God who takes away the sin…”
This is the heart of His mission.
The Greek expression here carries the idea of lifting up, bearing, and removing. Jesus came not merely to discuss sin or expose sin, but to bear it away.
There is an echo here of both sacrifice and scapegoat imagery from the Old Testament. On the Day of Atonement, sin was symbolically transferred and removed. In Christ, what was pictured in shadow is accomplished in reality.
He takes away sin.
Not merely the consequences of sin.
Not merely the feelings associated with sin.
Not merely the social damage of sin.
He deals with sin itself.
And notice the word is singular: “sin.”
This points not only to individual acts, but to the whole burden and reality of human rebellion against God.
1 Peter 2:24 (NLT): “He personally carried our sins in his body on the cross so that we can be dead to sin and live for what is right. By his wounds you are healed.”
Peter writes to suffering believers and points them back to the cross. The phrase “He personally carried” is sacrificial language. Jesus did not deal with sin abstractly. He carried it concretely, bodily, substitutionally, on the cross.
And notice the purpose: not only forgiveness, but transformation. He bore our sins so that we might die to sin and live righteously.
This is vital for discipleship. The Lamb does not only pardon us; He changes us.
Charles Stanley said, “The cross shows us the seriousness of our sin, but it also shows us the immeasurable love of God.”
That is exactly what John 1:29 proclaims. The Lamb reveals both the horror of sin and the glory of grace. At Calvary, justice and mercy kissed. Holiness was upheld. Love was poured out. The sinner’s debt was borne by the sinless Son.
Imagine a child drawing over a priceless masterpiece with a marker pen. The damage cannot simply be ignored. The wrong must be dealt with. Now imagine the owner of that masterpiece stepping forward and saying, “I will bear the cost of restoration myself.”
That is only a faint picture, but it helps us. Sin is real damage before a holy God. The cross is not God pretending it does not matter. The cross is God Himself, in the person of His Son, bearing the cost to restore what we ruined.
There are people listening today who still carry sins that Jesus came to take away. You carry old guilt, secret shame, hidden habits, uncleanness of mind, bitterness of heart, pride, unbelief, lust, anger, envy, and fear. You carry the burden as though you were meant to drag it all your days.
But hear the Gospel: the Lamb of God takes away sin.
Not covers it temporarily only.
Not delays judgment only.
Not manages symptoms only.
He takes it away.
That does not mean there is no battle in the Christian life. There is. But the dominion of sin is broken for those who are in Christ. The penalty has been paid. The stain is cleansed. The record is cancelled. The conscience can be washed. The sinner can be forgiven.
4. See the Glory of the Gospel: For the World
John says, “who takes away the sin of the world!”
This does not mean every individual is automatically saved regardless of repentance and faith. The rest of John’s Gospel makes abundantly clear the necessity of believing in Christ. But it does mean that Jesus is not a tribal saviour, a local redeemer, or a Messiah for one ethnic group alone. He is the Saviour for Jew and Gentile, for every nation, every background, every class, every kind of sinner who will come to Him in faith.
This is glorious.
The Gospel is wide enough for the world and specific enough for you.
Revelation 5:9 (NLT): “And they sang a new song with these words: ‘You are worthy to take the scroll and break its seals and open it. For you were slaughtered, and your blood has ransomed people for God from every tribe and language and people and nation.’”
The Lamb is worthy because the Lamb was slain. His blood has purchased a people from every tribe and language and people and nation. That is the triumph of the Gospel. Jesus did not come merely to improve one corner of the world. He came to redeem a people for God from across the earth.
John 3:16–17 (NLT): “For this is how God loved the world: He gave his one and only Son, so that everyone who believes in him will not perish but have eternal life. God sent his Son into the world not to judge the world, but to save the world through him.”
Here again we see both breadth and clarity. God loved the world. The offer is gloriously wide. But the saving benefit belongs to “everyone who believes in him.” The Gospel must be preached to all, and all who repent and believe will be saved.
The Greek word kosmos for “world” often carries the sense of the fallen human order in rebellion against God. That makes the grace even more astonishing. Christ came not because the world was lovely, but because the world was lost.
This matters deeply for discipleship. If Jesus is the Lamb for the world, then the church must never become inward-looking, self-protective, or spiritually selfish. We are not merely to admire the Lamb; we are to announce the Lamb.
The church does not exist to preserve religious comfort.
The church exists to proclaim Christ crucified and risen.
We are called to take the message of the Lamb into our homes, our streets, our communities, our workplaces, and the nations.
Max Lucado wrote, “God loves you just the way you are, but He refuses to leave you that way. He wants you to be just like Jesus.”
That is wonderfully pastoral. The Lamb receives sinners from the world, but He does not leave them in the bondage of the world. He saves us, sanctifies us, and shapes us into His likeness. That is discipleship: saved by the Lamb, then formed by the Lamb, then sent for the Lamb.
5. The Gospel at the Heart of John 1:29
Let us now draw the threads together.
John 1:29 is not merely a title for Jesus. It is a summary of the Gospel.
Jesus is the Lamb.
That means He is the sacrifice appointed by God.
He takes away sin.
That means He bears the guilt, penalty, and judgment that sinners deserve.
He does this for the world.
That means the Gospel is for all who will come to Him by faith.
And how did He accomplish this?
He went to the cross.
He who was born in Bethlehem came to die at Calvary.
He who was praised by angels would be rejected by men.
He who knew no sin would be made sin for us.
He who is eternally pure would bear our impurity.
He who is the Son of God would die in the place of sinners.
2 Corinthians 5:21 (NLT): “For God made Christ, who never sinned, to be the offering for our sin, so that we could be made right with God through Christ.”
This is the great exchange. Christ takes our sin; we receive His righteousness. He bears what was ours so that we might receive what is His.
Romans 5:8 (NLT): “But God showed his great love for us by sending Christ to die for us while we were still sinners.”
Notice that Christ did not die for us when we had improved enough, cleaned ourselves up enough, or become religious enough. He died for us while we were still sinners. That is grace.
1 Corinthians 15:3–4 (NLT): “I passed on to you what was most important and what had also been passed on to me. Christ died for our sins, just as the Scriptures said. He was buried, and he was raised from the dead on the third day, just as the Scriptures said.”
There is the Gospel plainly stated:
Christ died for our sins.
He was buried.
He was raised on the third day.
The Lamb who was slain is now risen and exalted. He is not merely the crucified Saviour; He is the living Lord. The cross was not the end. The tomb is empty. Jesus is alive. The Lamb upon the throne is also the Shepherd of His people.
6. Two Illustrations for the Heart
Illustration One: The Bridge That Held
Imagine a man trying to cross a deep ravine. He sees many things scattered near the edge: ropes, planks, stones, even signs promising a way across. But none of them can carry him. Then he sees a solid bridge spanning the entire gap from one side to the other.
Now the question is not whether he admires the bridge. The question is whether he trusts it enough to step onto it.
Many people admire Jesus. They respect Him, quote Him, display Him at Christmas, mention Him at funerals, and speak well of Him in polite conversation. But admiration is not salvation. The question is: have you trusted Him? Have you stepped fully onto Christ as your only hope of forgiveness and eternal life?
The Lamb of God is not merely to be admired from a distance. He is to be trusted completely.
Illustration Two: The Stain That Would Not Wash Out
Imagine a white garment stained deeply and permanently. You try soap, scrubbing, bleaching, and every human remedy, but the stain remains. Then someone comes with a cleansing agent strong enough not merely to fade the stain but to remove it completely.
Sin is like that stain. Human effort cannot wash it out. Good works cannot erase it. Time cannot fade it. Religion cannot hide it. But the blood of Jesus Christ cleanses from all sin.
1 John 1:7 (NLT): “But if we are living in the light, as God is in the light, then we have fellowship with each other, and the blood of Jesus, his Son, cleanses us from all sin.”
That is not partial cleansing. That is not selective cleansing. That is not cleansing for respectable sins only. That is cleansing from all sin.
7. What This Means for Discipleship
The series is called Discipleship (Following Jesus), so we must not stop at conversion alone. John 1:29 has profound implications for how we live as followers of Christ.
A. Follow the Lamb in Humble Gratitude
A disciple never gets over being saved. We do not move on from the cross; we move deeper into its wonder. The Lamb of God must remain central in our worship, our prayer, our obedience, and our witness.
If Jesus took away your sin, then you do not belong to yourself anymore. You belong to Him.
B. Fight Sin Because the Lamb Died for It
How can we casually flirt with what nailed our Saviour to the cross? How can we make peace with the very thing He came to take away?
This does not mean believers never struggle. We do struggle. But we now struggle from a position of grace and victory, not slavery and despair.
Romans 6:11–12 (NLT): “So you also should consider yourselves to be dead to the power of sin and alive to God through Christ Jesus. Do not let sin control the way you live; do not give in to sinful desires.”
Because of the Lamb, sin is no longer your master. Therefore do not yield to it. That is discipleship in the twenty-first century: resisting the pressure of a culture that normalises impurity, relativism, self-rule, greed, and godlessness, and instead living in joyful submission to Jesus.
C. Proclaim the Lamb Boldly
John the Baptist pointed away from himself and toward Jesus. So must we.
In an age of spiritual confusion, the church must speak clearly.
We do not merely offer advice. We proclaim Christ.
We do not merely discuss morality. We preach the Lamb.
We do not merely defend religion. We announce salvation in Jesus.
R. T. Kendall said, “The greatest proof of the Holy Spirit in your life is not power, but Christlikeness.”
That is so important. The Spirit’s work is to glorify Christ, and one evidence of genuine discipleship is that our lives increasingly point others to Jesus rather than ourselves. A true disciple becomes, in a smaller way, what John the Baptist was: a witness to the Lamb.
D. Rest in the Finished Work of Christ
There are many believers who love Jesus, yet live under constant condemnation. They know the truth of the cross in doctrine, but not always in daily peace.
John 1:29 reminds us that Jesus takes away sin. If you are in Christ, your guilt is not waiting to be paid again. Your debt is not hanging over you. Your condemnation has been dealt with at Calvary.
Romans 8:1 (NLT): “So now there is no condemnation for those who belong to Christ Jesus.”
Not less condemnation.
Not reduced condemnation.
No condemnation.
That should produce humility, holiness, joy, and freedom in the heart of every disciple.
8. A Clear Gospel Invitation
Perhaps someone listening today has never truly come to Jesus Christ. You know about Him, but you do not yet know Him. You have heard sermons, sung hymns, perhaps attended church for years, but you have never surrendered your life to the Lamb of God.
Hear the Word of the Lord today:
Your sin is real.
Your guilt is serious.
Judgment is coming.
You cannot save yourself.
But God, in His mercy, has sent His Son.
Jesus Christ, the Lamb of God, lived the sinless life you could never live. He died on the cross for sinners. He was buried. He rose again on the third day. He is alive forevermore. And He now calls you to repent and believe the Gospel.
To repent means to turn from sin, self-rule, and unbelief.
To believe means to trust wholly in Jesus Christ as your Saviour and Lord.
Do not merely admire the Lamb.
Do not merely study the Lamb.
Do not merely sing about the Lamb.
Come to the Lamb.
Acts 3:19 (NLT): “Now repent of your sins and turn to God, so that your sins may be wiped away.”
That is the promise. Not managed. Not hidden. Not delayed. Wiped away.
If today you know the Spirit of God is calling you, then respond. Turn from your sin. Place your faith in Jesus. Ask Him to forgive you, cleanse you, save you, and rule over your life.
And dear believer, perhaps you do know Christ, but you have wandered. Then hear this call afresh: come back to the Lamb. There is mercy for the repentant. There is cleansing for the confessing. There is restoration for the returning.
9. A Call to Action for Believers
Let me speak plainly and pastorally.
Because Jesus is the Lamb of God:
1. Worship Him deeply.
Do not let the cross become familiar in a cold way. Stand again in wonder at what it cost to save you.
2. Repent quickly.
If there is known sin in your life, do not excuse it. Bring it into the light. The Lamb came to take away sin, not to make room for it.
3. Follow Him obediently.
Discipleship is not sentimental admiration. It is surrender. Ask in every area of life: “Lord Jesus, what would it mean for me to follow You here?”
4. Witness to others boldly.
There are people around you carrying sin that only Jesus can remove. Point them to the Lamb.
5. Rest in His grace daily.
Do not live as though your standing with God depends on your performance. It depends on Christ’s finished work.
Conclusion: Behold Him Again
John the Baptist’s cry still rings out today:
“Look! The Lamb of God who takes away the sin of the world!”
Look to Him, weary sinner.
Look to Him, struggling saint.
Look to Him, doubting heart.
Look to Him, wandering believer.
Look to Him, church of Jesus Christ.
He is the Lamb provided by God.
He is the Lamb prophesied in Scripture.
He is the Lamb sacrificed for sin.
He is the Lamb risen in victory.
He is the Lamb enthroned in glory.
And one day, by grace, all His redeemed people will behold Him face to face.
Final Exhortation / Benediction
So go from this place with your eyes fixed on Jesus.
When guilt accuses, behold the Lamb.
When temptation rises, behold the Lamb.
When fear overwhelms, behold the Lamb.
When the world distracts, behold the Lamb.
When ministry grows heavy, behold the Lamb.
When death itself draws near, behold the Lamb.
And may the Lord grant that we, as His disciples, would live with hearts cleansed by His blood, mouths filled with His praise, feet ready to follow His steps, and lives gladly surrendered to His will.
For worthy is the Lamb who was slain.
Worthy is the Lamb who lives forever.
Worthy is the Lamb who takes away sin.
And worthy is the Lamb to receive your trust, your obedience, your worship, and your whole life.
In the name of Jesus Christ our Lord. Amen.
