For we know that our old self was crucified with him so that the body of sin might be done away with, that we should no longer be slaves to sin -- because anyone who has died has been freed from sin.
Romans 6:6,7 NIV

My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous: And he is the propitiation for our sins: and not for our's only, but also for the sins of the whole world. And hereby we do know that we know him, if we keep his commandments.
1 John 2:1-3 KJV
