Jesus the Lamb of God

Scripture

John 1:20-34

Commentary

As John encounters Jesus he declares that Jesus is the Lamb of God who takes away the sins of the world.  It is possible that John does not fully understand the implications of this statement as he later sends his disciples to Jesus to ask if He was the one he was waiting for. 

Ultimately, Jesus would take the place of the sacrificial lamb.  He would die on the cross at the same time as the Passover lambs were being slaughtered at the temple.  Because Jesus is the lamb of God, He is a once for all sacrifice.  No other sacrifices are needed and nothing needs to be repeated.
