John 9:24-27

So a second time they called the man who had been [born] blind, and said to him, “Give God glory and praise [for your sight]! We know this Man [Jesus] is a sinner [separated from God].” Then he answered, “I do not know whether He is a sinner [separated from God]; but one thing I do know, that though I was blind, now I see.” So they said to him, “What did He [actually] do to you? How did He open your eyes?” He answered, “I already told you and you did not listen. Why do you want to hear it again and again? Do you want to become His disciples, too?”
