And Romans 12:1-2 mentions...

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 changes yourselves to be like the people of this world, but 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.
