John 9:18-21

18They still did not believe that he had been blind and had received his sight until they sent for the man’s parents. 19“Is this your son?” they asked. “Is this the one you say was born blind? How is it that now he can see?” 20“We know he is our son,” the parents answered, “and we know he was born blind. 21But how he can see now, or who opened his eyes, we don’t know. Ask him. He is of age; he will speak for himself.”
