24A second time they (Pharisees)summoned the man who had been blind. "Give glory to God," they said. "We know this man is a sinner."
25He replied, "Whether he is a sinner or not, I don't know. One thing I do know. I was blind but now I see!"
26Then they asked him, "What did he do to you? How did he open your eyes?"
27He answered, "I have told you already and you did not listen. Why do you want to hear it again? Do you want to become his disciples, too?"
Now THAT'S going to make a Pharisee bent on taking Jesus down real happy!
But seriously, it is a good representation of what happens when Jesus heals us (maybe not from physical blindness). We gain an understanding about Him that we didn't have before. We sometimes have to take on doubters of what is going on. And then Jesus is around to make sure we are ok.
This can also be applied to spiritual blindness.
