John 9:17-27

They said to the blind man again, “What do you say about Him because He opened your eyes?” He said, “He is a prophet.” But the Jews did not believe concerning him, that he had been blind and received his sight, until they called the parents of him who had received his sight. And they asked them, saying, “Is this your son, who you say was born blind? How then does he now see?” His parents answered them and said, “We know that this is our son, and that he was born blind; but by what means he now sees we do not know, or who opened his eyes we do not know. He is of age; ask him. He will speak for himself.” His parents said these things because they feared the Jews, for the Jews had agreed already that if anyone confessed that He was Christ, he would be put out of the synagogue. Therefore his parents said, “He is of age; ask him.” So they again called the man who was blind, and said to him, “Give God the glory! We know that this Man is a sinner.” He answered and said, “Whether He is a sinner or not I do not know. One thing I know: that though I was blind, now I see.” Then they said to him again, “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? Do you also want to become His disciples?”
