John 9:35-38 says:
35Jesus heard that the Jewish leaders had forced the man to leave. Jesus found the man and said to him, "Do you believe in the Son of Man?" 36The man asked, "Who is the Son of Man, sir? Tell me, so I can believe in him!"37Jesus said to him, "You have already seen him. The Son of Man is the one talking with you now." 38The man answered, "Yes, I believe, Lord!" Then the man bowed and worshiped Jesus. (Easy-to-Read Version)
King James Version: 35Jesus heard that they had cast him out; and when he had found him, he said unto him, Dost thou believe on the Son of God? 36He answered and said, Who is he, Lord, that I might believe on him? 37And Jesus said unto him, Thou hast both seen him, and it is he that talketh with thee. 38And he said, Lord, I believe. And he worshipped him.
