Romans 6:12-15

Let not sin therefore reign in your mortal body, that ye should obey the lusts thereof: neither present your members unto sin as instruments of unrighteousness; but present yourselves unto God, as alive from the dead, and your members as instruments of righteousness unto God. For sin shall not have dominion over you: for ye are not under law, but under grace. What then? shall we sin, because we are not under law, but under grace? God forbid.
