John 9:25-27

25 He replied, “Whether he is a sinner or not, I don’t know. One thing I do know. I was blind but now I see!”

26 Then they asked him, “What did he do to you? How did he open your eyes?”

27 He answered, “I have told you already and you did not listen. Why do you want to hear it again? Do you want to become his disciples too?”
