John 9:2-3, 34-38

And his disciples asked him, “Rabbi, who sinned, this man or his parents, that he was born blind?” Jesus answered, “It was not that this man sinned, or his parents, but that the works of God might be displayed in him.

They answered him, “You were born in utter sin, and would you teach us?” And they cast him out. Jesus heard that they had cast him out, and having found him he said, “Do you believe in the Son of Man?” He answered, “And who is he, sir, that I may believe in him?” Jesus said to him, “You have seen him, and it is he who is speaking to you.” He said, “Lord, I believe,” and he worshiped him.
