35 When Jesus heard what had happened, he found the man and asked, "Do you believe in the Son of Man? " 36 The man answered, "Who is he, sir? I want to believe in him." 37 "You have seen him," Jesus said, "and he is speaking to you!" 38 "Yes, Lord, I believe!" the man said. And he worshiped Jesus.
39 Then Jesus told him, "I entered this world to render judgment-to give sight to the blind and to show those who think they see that they are blind." 40 Some Pharisees who were standing nearby heard him and asked, "Are you saying we're blind?" 41 "If you were blind, you wouldn't be guilty," Jesus replied. "But you remain guilty because you claim you can see.

Commentary on John 9:35-38
(Read John 9:35-38)
Christ owns those who own him and his truth and ways. There is particular notice taken of such a suffer in the cause of Christ, and for the testimony of a good conscience. Our Lord Jesus graciously reveals himself to the man. Now he was made sensible what an unspeakable mercy it was, to be cured of his blindness, that he might see the Son of God. None but God is to be worshipped; so that in worshipping Jesus, he owned him to be God. All who believe in him, will worship him.
Commentary on John 9:39-41
(Read John 9:39-41)
Christ came into the world to give sight to those who were spiritually blind. Also, that those who see might be made blind; that those who have a high conceit of their own wisdom, might be sealed up in ignorance. The preaching of the cross was thought to be folly by such as by carnal wisdom knew not God. Nothing fortifies men's corrupt hearts against the convictions of the word, more than the high opinion which others have of them; as if all that gained applause with men, must obtain acceptance with God. Christ silenced them. But the sin of the self-conceited and self-confident remains; they reject the gospel of grace, therefore the guilt of their sin remains unpardoned, and the power of their sin remains unbroken.
