John 9:16, 30-33

Then some of the Pharisees said, “This Man [Jesus] is not from God, because He does not keep the Sabbath.” But others said, “How can a man who is a sinner (a non-observant Jew) do such signs and miracles?” So there was a difference of opinion among them.

The man replied, “Well, this is astonishing! You do not know where He comes from, and yet He opened my eyes! We know [according to your tradition] that God does not hear sinners; but if anyone fears God and does His will, He hears him. Since the beginning of time it has never been heard that anyone opened the eyes of a person born blind. If this Man were not from God, He would not be able to do anything [like this because God would not hear His prayer].”
