Romans 12:1-4

So brothers and sisters, 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, which 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; you will know what is good and pleasing to him and what is perfect. Because God has given me a special gift, I have something to say to everyone among you. Do not think you are better than you are. You must decide what you really are by the amount of faith God has given you. Each one of us has a body with many parts, and these parts all have different uses.
