'Sinner' in the Bible

Then some of the Pharisees began to say, "This man is not from God, because he does not observe the Sabbath." But others said, "How can a man who is a sinner perform such miraculous signs?" Thus there was a division among them.

Then they summoned the man who used to be blind a second time and said to him, "Promise before God to tell the truth. We know that this man is a sinner."

He replied, "I do not know whether he is a sinner. I do know one thing -- that although I was blind, now I can see."
