John 9:21

21 But we do not know how it is that he is now able to see, nor do we know who cured him of his blindness. Ask him; he is old enough, and he can answer for himself!"

John 9:21 In-Context

19 and asked them, "Is this your son? You say that he was born blind; how is it, then, that he can now see?"
20 His parents answered, "We know that he is our son, and we know that he was born blind.
21 But we do not know how it is that he is now able to see, nor do we know who cured him of his blindness. Ask him; he is old enough, and he can answer for himself!"
22 His parents said this because they were afraid of the Jewish authorities, who had already agreed that anyone who said he believed that Jesus was the Messiah would be expelled from the synagogue.
23 That is why his parents said, "He is old enough; ask him!"
