'Sinning' in the Bible

knowing that such a person is perverted and is sinning, being self-condemned.

The one who practices sin is of the devil, because the devil has been sinning from the beginning. For this [reason] the Son of God was revealed: in order to destroy the works of the devil.

If anyone should see his brother sinning a sin not [leading] to death, he should ask, and he will grant life to him, to those who sin not [leading] to death. ([There] is a sin [leading] to death; I do not say that he should ask about that.
