Romans 6:
12: Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof.
13: Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God.
14: For sin shall not have dominion over you: for ye are not under the law, but under grace.
15: What then? shall we sin, because we are not under the law, but under grace? God forbid.
16: 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?
17: But God be thanked, that ye were the servants of sin, but ye have obeyed from the heart that form of doctrine which was delivered you.
18: Being then made free from sin, ye became the servants of righteousness.
