Jesus heard that they had cast him out; and finding him, he said, Dost thou believe on the Son of God? He answered and said, And who is he, Lord, that I may believe on him? Jesus said unto him, Thou hast both seen him, and he it is that speaketh with thee. And he said, Lord, I believe. And he worshipped him. And Jesus said, For judgment came I into this world, that they that see not may see; and that they that see may become blind. Those of the Pharisees who were with him heard these things, and said unto him, Are we also blind? Jesus said unto them, If ye were blind, ye would have no sin: but now ye say, We see: your sin remaineth.
