Romans 6:16-20

16Know ye not that to whom ye yield yourselves bondmen for obedience, ye are bondmen to him whom ye obey, whether of sin unto death, or of obedience unto righteousness?

17But thanks [be] to 1God, that ye were bondmen of sin, but have obeyed from the heart the form of teaching into which ye were instructed.

18Now, having got your freedom from sin, ye have become bondmen to righteousness.

19I speak humanly on account of the weakness of your flesh. For even as ye have yielded your members in bondage to uncleanness and to lawlessness unto lawlessness, so now yield your members in bondage to righteousness unto holiness.

20For when ye were bondmen of sin ye were free from righteousness.
