John 9: 35-41
35Jesus heard that they had thrown him out, and when he found him, he said, "Do you believe in the Son of Man?"
36"Who is he, sir?" the man asked. "Tell me so that I may believe in him."
37Jesus said, "You have now seen him; in fact, he is the one speaking with you."
38Then the man said, "Lord, I believe," and he worshiped him.
39Jesus said, "For judgment I have come into this world, so that the blind will see and those who see will become blind."
40Some Pharisees who were with him heard him say this and asked, "What? Are we blind too?"
41Jesus said, "If you were blind, you would not be guilty of sin; but now that you claim you can see, your guilt remains.
