Then they took the man who had been blind to the Pharisees, because it was on the Sabbath that Jesus had made the mud and healed him. Therefore the Pharisees also asked him how he had received his sight. "He put mud on my eyes," the man replied, "and I washed, and now I see." Some of the Pharisees said, "This man Jesus is not from God, for he is working on the Sabbath." Others said, "But how could an ordinary sinner do such miraculous signs?" So there was a deep division of opinion among them. Then the Pharisees again questioned the man who had been blind and demanded, "What's your opinion about this man who healed you?" The man replied, "I think he must be a prophet." The Jewish leaders still refused to believe the man had been blind and could now see, so they called in his parents. They asked them, "Is this your son? Was he born blind? If so, how can he now see?" His parents replied, "We know this is our son and that he was born blind, but we don't know how he can see or who healed him. Ask him. He is old enough to speak for himself." His parents said this because they were afraid of the Jewish leaders, who had announced that anyone saying Jesus was the Messiah would be expelled from the synagogue. That's why his parents said, "He is of age. Ask him."
So for the second time they called in the man who had been blind and told him, "God should get the glory for this, because we know this man Jesus is a sinner." 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!" They were saying to him again, “What did jesus do to you? How did he open your eyes for you?” He said to them, “I told you and you were not listening. Why do you want to hear again? Do you also want to become his disciples?” Then they cursed him and said, "You are his disciple, but we are disciples of Moses! We know God spoke to Moses, but we don't even know where this man comes from." That man answered and said, “This is therefore to be marveled at, that you do not know from where he is and he opened my eyes.” “But we know that God does not listen to the voice of a sinner, but listens to whoever worships him and does his will.” Ever since the world began, no one has been able to open the eyes of someone born blind. If this man were not from God, he couldn't do anything like that." "You were born a total sinner!" they answered. "Are you trying to teach us?" And they threw him out of the synagogue.
And jesus heard that they had cast him out, and he found him and said to him, “Do you believe in the Son of God?” He who had been healed answered and said, “Who is He, my lord, that I may trust in him? jesus said to him, “You have seen him, and he is The One who is speaking with you.” he said, “I believe, my Lord”, and falling down, he worshiped him.. jesus said:" And jesus said, “For the judgment of this world I have come, that those who do not see may see, and that those who see may become blind.”
Some Pharisees who were standing nearby heard him and asked, "Are you saying we're blind?" jesus said to them, “If you were blind, you would not have sin, but now you say, 'We see.' Because of this, your sin stands.”
