John 9:23-27

For this reason his parents said, “He is of age; ask him.” So a second time they called the man who had been blind, and said to him, “Give glory to God; we know that this man is a sinner.” He then answered, “Whether He is a sinner, I do not know; one thing I do know, that though I was blind, now I see.” So they said to him, “What did He do to you? How did He open your eyes?” He answered them, “I told you already and you did not listen; why do you want to hear it again? You do not want to become His disciples too, do you?”
