Romans 6:12-14

Therefore do not let sin reign in your mortal body, so that you obey  its desires. And do not offer any parts  of it to sin  as weapons for unrighteousness. But as those who are alive from the dead, offer yourselves to God,  and all the parts of yourselves to God as weapons for righteousness. For sin will not rule over you, because you are not under the law  but under grace.
