Romans 6:15-16

Romans 6:15-16. God forbid. Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?

If you are doing the deeds of sin, you are the servants of sin and only as you are doing the will of God can you claim to be the servant of God. "Hereby we know that we know him, if we keep his commandments." That becomes the index of our condition. The man, then, that lives in sin and loves it, need not talk about the grace of God he is a stranger to it, for the mark of those that come under grace is this, that they serve God, and no longer serve sin.
