'Sinner' in the Bible

So some of the Pharisees were saying, "This man is not from God, because he does not observe the Sabbath!" Others were saying, "How can a man [who is] a sinner perform such signs?" And there was a division among them.

So they summoned the man who had been blind for the second time and said to him, "Give glory to God! We know that this man is a sinner!"

Then that man replied, "Whether he is a sinner I do not know. One [thing] I know--that [although I] was blind, now I see!"
