Romans 6:15-16

15Someone might say: ‘So we have a new life because God is kind to us. God's Law that he gave to Moses does not rule us any more. Then maybe we should continue to do wrong things. It will not make any difference.’ No, that is not true!

16Remember this: When you agree to serve someone as a slave, you have to obey that person as your master. You may choose to serve sin as your master. If you do that, you will die. Or you may choose to obey God. If you do that, you will live in a way that is right.
