'Sinner' in the Bible

Therefore said some of the Pharisees, This man is not of God, because he keepeth not the sabbath day. Others said, How can a man that is a sinner do such miracles? And there was a division among them.

Then again called they the man that was blind, and said unto him, Give God the praise: we know that this man is a sinner.

He answered and said, Whether he be a sinner or no, I know not: one thing I know, that, whereas I was blind, now I see.
