John 8-9: The Blind will See

Although Jesus told the Pharisee's over and over again that the Father had sent him, they still did not understand.  Your testimony is not valid, they told him.  Even when he healed the man who was blind from birth, they did not understand or believe him.  They kept interrogating the blind man trying to get him to denounce Jesus, but he would not.  They they tried to trap his parents.  'We know he is out son, they told them, but how he can see or who opened his eyes, we don't know.  You'll have to ask him.'  So they asked the man who had been blind the second time to give the glory to God instead of Jesus because they knew that Jesus was a sinner, but the blind man would not take the bait.  He replied, “Whether he is a sinner or not, I don’t know. One thing I do know. I was blind but now I see!” (John 9:25 NIV)

This angered the Pharisees so that they threw the blind man out of the temple.  Jesus found him and asked him if he believed in the Son of Man..
  “Who is he, sir?” the man asked. “Tell me so that I may believe in him.”
   Jesus said, “You have now seen him; in fact, he is the one speaking with you.”
   Then the man said, “Lord, I believe,” and he worshiped him.
   Jesus said, “For judgment I have come into this world, so that the blind will see and those who see will become blind.”
   Some Pharisees who were with him heard him say this and asked, “What? Are we blind too?”
   Jesus said, “If you were blind, you would not be guilty of sin; but now that you claim you can see, your guilt remains. - John 9:36-41 NIV

'It s not a sin to be blind,' Jesus says.  Those who know they are blind are willing to ask for their sight.  The sin is to claim you can see when you cannot.  Jesus came to give sight to the blind.  There is nothing he can offer those who think they can see.
