John 9 is the ninth chapter of the Gospel of John in the New Testament of the Christian Bible. It maintains the previous chapter's theme "Jesus is light", recording the healing of an unnamed man who had been blind from birth, a miracle performed by Jesus, and their subsequent dealings with the Pharisees. The man born blind comes to complete faith in Jesus, while some of the Pharisees remain in their sin. The gospel identifies an unnamed "disciple whom Jesus loved" as its source and possible author. Early Christian tradition uniformly affirmed that John composed this Gospel.
