Romans 6:19

19It is difficult for you to understand these things, because you are still weak. So I am using a human picture of slaves to help you to understand better. At one time, you agreed to serve bad things as your master. You let your body do wrong and disgusting things. You continued to do more and more bad things. So now, you must use your body to serve what is right and good. Then you will live in a good way that pleases God.
