John 9 is about Jesus healing a man born blind. When Jesus' disciples ask if the man's blindness was due to his own or his parents' sins, Jesus says neither caused it, but it was so God's works could be displayed. Jesus heals the man by making mud and having him wash in the Pool of Siloam. Though the man receives physical sight, he requires further revelation from Jesus to believe. The Jewish leaders question the healing, which causes division.
