'Sinner' in the Bible

Some therefore of the Pharisees said, This man is not from God, because he keepeth not the sabbath. But others said, How can a man that is a sinner do such signs? And there was division among them.

So they called a second time the man that was blind, and said unto him, Give glory to God: we know that this man is a sinner.

He therefore answered, Whether he is a sinner, I know not: one thing I know, that, whereas I was blind, now I see.
