So when we were baptized, we were buried with Christ and shared his death. We were buried with Christ so that we could {be raised up and} live a new life. This happened the same as Christ was raised from death by the wonderful power of the Father.
We know that our old life died with Christ on the cross. This happened so that our sinful selves would have no power over us. And then we would not be slaves to sin.
Don't offer the parts of your body to serve sin. Don't use your bodies as things to do evil with. But you should offer yourselves to God. Be like people that have died and now live. Offer the parts of your body to God to be used for doing good.
Surely you know that when you give yourselves like slaves to obey someone, then you are really slaves of that person. The person you obey is your master. You can follow sin, or obey God. Sin brings spiritual death. But obeying God makes you right with him.
I explain this by using an example that people know. I explain it this way because it is hard for you to understand. In the past you offered the parts of your body to be slaves to sin and evil. You lived only for evil. In the same way now you must give yourselves to be slaves of goodness. Then you will live only for God.
