How do we know that Christ is the Lamb of God?

The designation of Christ as the 'Lamb of God' is profoundly significant within the Christian faith. This title is introduced in John 1:29, where John the Baptist proclaims, 'Behold the Lamb of God, which taketh away the sin of the world.' This declaration roots Christ's identity in the sacrificial system of the Old Testament, where lambs were offered as sin offerings. The requirements for these lambs, specifically that they be without blemish, pointed towards the perfect and sinless nature of Christ, which is further affirmed in 1 Peter 1:18-19, stating that believers were redeemed 'with the precious blood of Christ, as of a lamb without blemish and without spot.'

Furthermore, the significance of the blood of the Lamb in the Passover narrative illustrates how Christ's sacrificial death serves as the ultimate fulfillment of these Old Testament sacrifices. He is the one whose blood covers the sins of His people, ensuring their protection from God's wrath, as outlined in Exodus 12:13. Thus, Jesus embodies the ultimate fulfillment of God's redemptive plan, evidenced through His sacrificial role as the Lamb, making Him central to salvation history.
