Salvation in Christ is not essentially about sin. God does not save you because you throw away your sin, or because you are able to stop sinning. Salvation is about your yielding to Him in repentance. Big difference.
Saying no to Jesus is a dead faith with dead works
God calls His followers to reject sin (2 Corinthians 7:1), all that He calls “sin”, and press on to our upward calling (Philippians 3:12-14). Fake faith does not fool God.
