An underlying theme in the Gospel of John is established at the very beginning in 1:5, "And the light shines in the darkness, and the darkness did not comprehend it." The identity of Jesus remains a mystery to all even John until God reveals Jesus. This is not to say that John did not know Jesus the man as described in the Gospel of Matthew but rather the divinity of Jesus is hidden. The story of Jesus baptism is therefore told as a flash back with John repeating twice "I myself did not know him". It was only through revelation of the Spirit descending that the divinity of Jesus was made known to John. This divinity was not revealed as power but as the Lamb of God whose death would take away the sin of the world and not just the Jewish people. John told his disciples that Jesus was the "Lamb of God" but they still did not understand what they were looking for so Jesus asks them. They still don't see him calling him "Rabbi" and he invites them to "Come and See". Andrew, however, recognized Jesus as the Messiah.
