Romans 6
16 Ref Don't you know that to whom you present yourselves as servants to obedience, his servants you are whom you obey; whether of sin to death, or of obedience to righteousness?
17 Ref But thanks be to God, that, whereas you were bondservants of sin, you became obedient from the heart to that form of teaching whereunto you were delivered.
18 Ref Being made free from sin, you became bondservants of righteousness.
