John 1:35-42 Behold, Jesus is the Lamb of God

John was standing with two of his disciples,
and as he watched Jesus walk by, he said,
"Behold, the Lamb of God."
The two disciples heard what he said and followed Jesus.
Jesus turned and saw them following him and said to them,
"What are you looking for?"
They said to him, "Rabbi" - which translated means Teacher -,
"where are you staying?"
He said to them, "Come, and you will see."
So they went and saw where Jesus was staying,
and they stayed with him that day.
It was about four in the afternoon.
Andrew, the brother of Simon Peter,
was one of the two who heard John and followed Jesus.
He first found his own brother Simon and told him,
"We have found the Messiah" - which is translated Christ -.
Then he brought him to Jesus.
Jesus looked at him and said,
"You are Simon the son of John;
you will be called Cephas" - which is translated Peter.

In this passage we see Jesus' call and his disciples responses. In these call stories, Jesus does not force the disciples to follow him but rather invites them. He shows them the meaning of the Kingdom of God rather than simply lecture or preach. Jesus is a true teacher because he leads by example. Here we also see Jesus being called the Lamb of God. This is because it is with his sacrifice our sins will be washed away. He is the sacrificial lamb who takes away the sin of the world. He is the lamb who is sacrificed at the temple for the people. This is why in iconography the symbol of Jesus was often a lamb with a banner or chi rho.
