The Gospel of John is slightly different from the other three Gospels. The other Gospels focus on events of Jesus' life, John focuses on the meaning of who He is and what He said and did. We often wonder what God is like, and we're taught to look at Jesus, because He is God and shows us what God is like. On seven occasions Jesus said, "I am." Each one of these is recorded in John. Jesus' seven "I ams" tell us a great deal about His divine character.
