“All unrighteousness is sin: and there is a sin not unto death.”
King James Version (KJV)
5:17 All deviation from perfect holiness is sin; but all sin is not unpardonable.
1Jo 5:17 All unrighteousness is sin. All wrong doing is sin, but the condition of soul that sets it against righteousness and against Christ as steel is a sin unto death. Such a soul repels Christ the life.
