John 9:35-41

35Jesus heard that they had cast him out, and having found him, he said to him, Thou, dost thou believe on the Son of 1God? 36He answered and said, And who is he, Lord, that I may believe on him? 37And Jesus said to him, Thou hast both seen him, and he that speaks with thee is he. 38And he said, I believe, Lord: and he did him homage. 39And Jesus said, For judgment am I come into this world, that they which see not may see, and they which see may become blind. 40And [some] of the Pharisees who were with him heard these things, and they said to him, Are we blind also? 41Jesus said to them, If ye were blind ye would not have sin; but now ye say, We see, your sin remains.
