John 9 tells of the sixth sign in John's Gospel, and it is also a story about seeing. The disciples asked who sinned, the man or his parents. Jesus said neither. This man's blindness would display God's works. Jesus, the light of the world, made clay and anointed the man's eyes, much as God formed Adam from the ground. He sent him to wash in Siloam, meaning Sent. The man obeyed and came back seeing.
The Pharisees could not deny the miracle, so they attacked it. Jesus had made clay on the Sabbath. They argued among themselves. They interrogated the man's parents, who feared being expelled from the synagogue. Twice they questioned the man. His understanding of Jesus grew. First he called Him a man called Jesus, then a prophet, and then a man from God. He said, One thing I do know, that though I was blind, now I see. The leaders insulted him and drove him out.
When the synagogue rejected him, Jesus sought him out. Jesus asked, Do you believe in the Son of God? The man said, Lord, I believe! and he worshiped him. Jesus explained the deeper lesson. He came so that those who do not see may see, and those who see may become blind. The proud Pharisees claimed they could see. Because they refused to admit their blindness, their sin remained. The humble beggar received both physical and spiritual sight.
