Romans 6:16

16 Do you not know that when you present yourselves to someone as slaves for obedience, you are slaves of the one whom you obey, either of sin resulting in death, or of obedience resulting in righteousness?

21 Therefore what benefit were you then deriving from the things of which you are now ashamed? For the outcome of those things is death.
