John 9:2-3, 34-38

And His disciples asked Him, “Rabbi, who sinned, this man or his parents, that he would be born blind?” Jesus answered, “It was neither that this man sinned, nor his parents; but it was so that the works of God might be displayed in him.

They answered him, “You were born entirely in sins, and are you teaching us?” So they put him out. Jesus heard that they had put him out, and finding him, He said, “Do you believe in the Son of Man?” He answered, “Who is He, Lord, that I may believe in Him?” Jesus said to him, “You have both seen Him, and He is the one who is talking with you.” And he said, “Lord, I believe.” And he worshiped Him.
