So then, my friends, because of God's great mercy to us I appeal to you: Offer yourselves as a living sacrifice to God, dedicated to his service and pleasing to him. This is the true worship that you should offer. Do not conform yourselves to the standards of this world, but let God transform you inwardly by a complete change of your mind. Then you will be able to know the will of God—what is good and is pleasing to him and is perfect.
