John 9:2-3, 34-38

And His disciples asked Him, saying, “Rabbi, who sinned, this man or his parents, that he was born blind?” Jesus answered, “Neither this man nor his parents sinned, but that the works of God should be revealed in him.

They answered and said to him, “You were completely born in sins, and are you teaching us?” And they cast him out. Jesus heard that they had cast him out; and when He had found him, He said to him, “Do you believe in the Son of God?” He answered and said, “Who is He, Lord, that I may believe in Him?” And Jesus said to him, “You have both seen Him and it is He who is talking with you.” Then he said, “Lord, I believe!” And he worshiped Him.
