John 9:35-41

35Jesus heard that they had cast him out; and finding him, he said, Dost thou believe on the Son of God? 36He answered and said, And who is he, Lord, that I may believe on him? 37Jesus said unto him, Thou hast both seen him, and he it is that speaketh with thee. 38And he said, Lord, I believe. And he worshipped him. 39And Jesus said, For judgment came I into this world, that they that see not may see; and that they that see may become blind. 40Those of the Pharisees who were with him heard these things, and said unto him, Are we also blind? 41Jesus said unto them, If ye were blind, ye would have no sin: but now ye say, We see: your sin remaineth.
