John 9:22

19 and asked them, "Is this your son, who you say was born blind? How then does he now see?"

20 His parents answered them, "We know that this is our son, and that he was born blind;

21 but how he now sees, we don`t know; or who opened his eyes, we don`t know. He is of age. Ask him. He will speak for himself."

22 His parents said these things because they feared the Jews; for the Jews had already agreed that if any man would confess him as Christ, he would be put out of the synagogue.

23 Therefore his parents said, "He is of age. Ask him."

24 So they called the man who was blind a second time, and said to him, "Give glory to God. We know that this man is a sinner."

25 He therefore answered, "I don`t know if he is a sinner. One thing I know: that though I was blind, now I see."
