Why is Jesus called the ‘Lamb of God’?
Question 3046
When John the Baptist saw Jesus approaching, he made one of the most profound declarations in all of Scripture: “Behold, the Lamb of God, who takes away the sin of the world!” (John 1:29). This title, ‘Lamb of God,’ reaches back through centuries of sacrificial imagery and forward to the eternal worship of heaven. But why a lamb? And what does this title tell us about who Jesus is and what He came to do?
The Lamb in Genesis: Substitution Introduced
The imagery of a lamb as a substitute for sinful humanity appears remarkably early in Scripture. When God expelled Adam and Eve from Eden, they had tried to cover their nakedness with fig leaves – their own effort to deal with shame. But God rejected this and “made for Adam and for his wife garments of skins and clothed them” (Genesis 3:21). Something had to die so they could be covered. The principle of substitutionary death was established from the very beginning.
This theme becomes explicit in Genesis 22, when God commanded Abraham to offer Isaac as a sacrifice. As they climbed Mount Moriah, Isaac asked the heartbreaking question: “Behold, the fire and the wood, but where is the lamb for a burnt offering?” (Genesis 22:7). Abraham’s answer was prophetic: “God will provide for himself the lamb for a burnt offering, my son” (Genesis 22:8). God did provide – a ram caught in a thicket substituted for Isaac. Abraham named the place יְהוָה יִרְאֶה (Yahweh Yireh), “The LORD will provide.” The question Isaac asked and the answer Abraham gave echo through the centuries: Where is the lamb? God will provide.
The Passover Lamb: Deliverance Through Blood
The most significant Old Testament background to ‘Lamb of God’ is the Passover. When God prepared to deliver Israel from Egyptian bondage, He commanded each household to take a lamb without blemish, slaughter it, and apply its blood to the doorposts and lintel of their homes. “The blood shall be a sign for you, on the houses where you are. And when I see the blood, I will pass over you, and no plague will befall you to destroy you, when I strike the land of Egypt” (Exodus 12:13).
The lamb died so that the firstborn would live. Its blood was the means of deliverance from judgment. This was not merely a one-time historical event but an annual reminder. Every year at Passover, Israel was to remember that they had been redeemed by the blood of a lamb.
The connection to Jesus is unmistakable. He was crucified at Passover. Paul explicitly states: “Christ, our Passover lamb, has been sacrificed” (1 Corinthians 5:7). John’s Gospel notes that Jesus died at the very hour when the Passover lambs were being slaughtered in the Temple (John 19:14). Just as the original Passover lamb’s bones were not to be broken (Exodus 12:46), so the soldiers did not break Jesus’ legs (John 19:36). The typology is precise and intentional. Jesus is the true Passover Lamb whose blood delivers us from the judgment of God.
Isaiah’s Suffering Servant
Perhaps the most poignant prophetic connection comes from Isaiah 53. Here the Servant of the LORD is described as one who “was oppressed, and he was afflicted, yet he opened not his mouth; like a lamb that is led to the slaughter, and like a sheep that before its shearers is silent, so he opened not his mouth” (Isaiah 53:7). The lamb imagery here emphasises innocence, gentleness, and willingness to suffer without resistance.
But this is no mere victim. Isaiah makes clear that the Servant’s suffering is substitutionary: “Surely he has borne our griefs and carried our sorrows… he was pierced for our transgressions; he was crushed for our iniquities; upon him was the chastisement that brought us peace, and with his wounds we are healed” (Isaiah 53:4–5). The Ethiopian eunuch was reading this very passage when Philip encountered him and “told him the good news about Jesus” (Acts 8:35). The connection between Isaiah’s suffering lamb and Jesus was evident to the earliest Christians.
The Lamb in Levitical Sacrifices
Throughout Leviticus, lambs were prescribed for various offerings. The daily tamid offering consisted of a lamb sacrificed each morning and evening (Exodus 29:38–42; Numbers 28:3–8). This meant that the altar was never without the blood of a lamb. The entire sacrificial system kept before Israel’s eyes the reality that sin requires death, that atonement comes through blood, and that something innocent must die in place of the guilty.
The requirements for sacrificial lambs pointed to Jesus. The animal must be “without blemish” (Leviticus 1:3, 10). Peter uses this very language: “You were ransomed… with the precious blood of Christ, like that of a lamb without blemish or spot” (1 Peter 1:18–19). Jesus lived a sinless life precisely so that He could be the perfect sacrifice – the Lamb truly without defect.
The Lamb in Revelation
The title ‘Lamb’ reaches its culmination in Revelation, where Jesus is called the Lamb (ἀρνίον, arnion) nearly thirty times. But this is no helpless victim. The Lamb in Revelation has “seven horns and seven eyes” (Revelation 5:6), symbolising complete power and complete knowledge. He alone is worthy to open the scroll that initiates God’s final judgments. The elders and angels worship Him singing: “Worthy is the Lamb who was slain, to receive power and wealth and wisdom and might and honour and glory and blessing!” (Revelation 5:12).
Here we see the full picture. The Lamb who was slain is now the Lamb on the throne. He executes judgment: the kings of the earth hide from “the wrath of the Lamb” (Revelation 6:16). He leads His people: “The Lamb in the midst of the throne will be their shepherd” (Revelation 7:17). He celebrates victory: “the marriage of the Lamb has come” (Revelation 19:7). And in the eternal state, “the throne of God and of the Lamb” will be the centre of the New Jerusalem, from which flows the river of life (Revelation 22:1, 3).
Why ‘Lamb of God’ Matters
John the Baptist’s declaration sums up the entire sacrificial system and all prophetic expectation. The Lamb of God is God’s own provision for human sin. He is not merely a lamb – He is the Lamb, the one to whom all others pointed. He takes away sin – not merely covers it temporarily as the Old Testament sacrifices did, but removes it entirely and forever. And He does this for the world – His death is sufficient for all humanity, available to all who believe.
When we call Jesus the Lamb of God, we confess that we are sinners who deserved judgment. We acknowledge that we could not save ourselves. And we trust in the one who died in our place, whose blood marks us as belonging to God, so that divine wrath passes over us. This is the heart of the Gospel: “Behold, the Lamb of God, who takes away the sin of the world!”
“Behold, the Lamb of God, who takes away the sin of the world!” John 1:29
