What does the Bible say about Jesus as the Lamb of God?

In John 1:29, John the Baptist exclaims, 'Behold, the Lamb of God, which taketh away the sin of the world.' This declaration points to Jesus as the ultimate sacrifice, a theme deeply rooted in the Old Testament where lambs were offered for sin. Throughout the scriptures, we see this typology, with Jesus fulfilling the role of the lamb that was prophesied to take away sin permanently, contrasting with the sacrificial lambs that were temporary and could not bear the weight of sin. This pivotal role asserts that through His sacrifice, Jesus accomplished redemption for His people and demonstrated the mercy and justice of God.
