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

The recognition of Jesus as the Lamb of God is rooted in Old Testament prophecies and fulfilled in the New Testament. John the Baptist famously proclaimed Jesus as the Lamb who takes away the sins of the world (John 1:29), connecting Him to the sacrificial lambs of the Old Covenant. Throughout Revelation, Jesus is depicted as the Lamb, emphasizing His sacrificial death and resurrection as the basis for the salvation of His people. This title underscores His role as both the perfect sacrifice and the mediator between God and humanity, fulfilling the redemptive plan set forth by God.
