Why is Jesus referred to as the Lamb of God?

The title 'Lamb of God' signifies Jesus' role as the ultimate sacrifice who takes away the sin of the world, as declared in John 1:29. This title ties back to the Passover lamb depicted in Exodus, whose blood signified protection and deliverance from judgment. Jesus’ sacrificial death not only fulfills the types and shadows of the Old Testament sacrifices but also illustrates His innocence and the gravity of sin's penalty. By being the Lamb, He embodies the perfect sacrifice that eternally resolves the tension between God’s justice and His mercy.
