From John 9:
“Jesus heard that they had cast him out; and when He had found him, He said to him, “Do you believe in the Son of God?”
36 He answered and said, “Who is He, Lord, that I may believe in Him?”
37 And Jesus said to him, “You have both seen Him and it is He who is talking with you.”
38 Then he said, “Lord, I believe!” And he worshiped Him.
39 And Jesus said, “For judgment I have come into this world, that those who do not see may see, and that those who see may be made blind.”
40 Then some of the Pharisees who were with Him heard these words, and said to Him, “Are we blind also?”
41 Jesus said to them, “If you were blind, you would have no sin; but now you say, ‘We see.’ Therefore your sin remains” (John 9:25-41).
