John 9:35-38 (KJV)
35 Jesus 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?
36 He answered and said, Who is he, Lord, that I might believe on him?
37 And Jesus said unto him, Thou hast both seen him, and it is he that talketh with thee.
38 And he said, Lord, I believe. And he worshipped him.
