John 9:26-41 (ESV)
26 They said to him, “What did he do to you? How did he open your eyes?” 27 He answered them, “I have told you already, and you would not listen. Why do you want to hear it again? Do you also want to become his disciples?” 28 And they reviled him, saying, “You are his disciple, but we are disciples of Moses. 29 We know that God has spoken to Moses, but as for this man, we do not know where he comes from.” 30 The man answered, “Why, this is an amazing thing! You do not know where he comes from, and yet he opened my eyes. 31 We know that God does not listen to sinners, but if anyone is a worshiper of God and does his will, God listens to him. 32 Never since the world began has it been heard that anyone opened the eyes of a man born blind. 33 If this man were not from God, he could do nothing.” 34 They answered him, “You were born in utter sin, and would you teach us?” And they cast him out.
35 Jesus heard that they had cast him out, and having found him he said, “Do you believe in the Son of Man?”  36 He answered, “And who is he, sir, that I may believe in him?” 37 Jesus said to him, “You have seen him, and it is he who is speaking to you.” 38 He said, “Lord, I believe,” and he worshiped him. 39 Jesus said, “For judgment I came into this world, that those who do not see may see, and those who see may become blind.”40 Some of the Pharisees near him heard these things, and said to him, “Are we also blind?” 41 Jesus said to them, “If you were blind, you would have no guilt;  but now that you say, ‘We see,’ your guilt remains.
