John 9: Jesus, the blind man and the Sabbath

In John 9, Jesus is in Jerusalem near the Pool of Siloam on Sabbath. There was a blind man there. Jesus healed him. According to the Pharisees, Jesus broke the law of keeping the Sabbath. A big discussion began: The blind man claimed that the Lord (the Father) is with Jesus given the great sign he had done on him, while the Pharisees claimed that Jesus was a sinner because he hadn't healed in a kosher way. The blind man was mistreated and expelled (from where they were). 

35 Jesus heard that they had thrown him out, and went and found him. He asked him, “Do you believe in the Son of Man?”
36 The man said, “Point him out to me, sir, so that I can believe in him.”
37 Jesus said, “You’re looking right at him. Don’t you recognize my voice?”
38 “Master, I believe,” the man said, and worshiped him.
39 Jesus then said, “I came into the world to bring everything into the clear light of day, making all the distinctions clear, so that those who have never seen will see, and those who have made a great pretense of seeing will be exposed as blind.”

The blind man was despised by that society because they saw him as someone cursed by the Lord for sins. By other hand, Jesus brought light to the man who lived in darkness. Do you believe in the Son of Man?
