John 9:19-21

9:19 They asked the parents, “Is this your son, whom you say was born blind? Then how does he now see?” 9:20 So his parents replied, “We know that this is our son and that he was born blind. 9:21 But we do not know how he is now able to see, nor do we know who caused him to see. Ask him, he is a mature adult. He will speak for himself.”
