Romans 12:1-5

So brothers, since God has shown us great mercy, I beg you to offer your lives as a living sacrifice to him. Your offering must be only for God and pleasing to him. This is the spiritual way for you to worship. Do not be shaped by this world. Instead be changed within by a new way of thinking. Then you will be able to decide what God wants for you. And you will be able to know what is good and pleasing to God and what is perfect. God has given me a special gift. That is why I have something to say to everyone among you. Do not think that you are better than you are. You must see yourself as you really are. Decide what you are by the amount of faith God has given you. Each one of us has a body, and that body has many parts. These parts all have different uses. In the same way, we are many, but in Christ we are all one body. Each one is a part of that body. And each part belongs to all the other parts.
