The Gospel of John was written by the Apostle John around 97 AD to prove that Jesus is the Christ and Son of God. It was written for a general Christian audience familiar with the other Gospels. John's Gospel emphasizes the deity of Christ through His miracles and divine claims. It recounts Jesus' ministry, rejection, crucifixion and resurrection. Key events include the wedding at Cana, Nicodemus' visit, Jesus' encounters in Samaria and Judea, the raising of Lazarus, His trials and crucifixion. The book ends with post-resurrection appearances of Jesus and His interaction with the disciples.
