Brothers and sisters, God has shown you his mercy. So I am asking you to offer up your bodies to him while you are still alive. Your bodies are a holy sacrifice that is pleasing to God. When you offer your bodies to God, you are worshiping him. Don't live any longer the way this world lives. Let your way of thinking be completely changed. Then you will be able to test what God wants for you. And you will agree that what he wants is right. His plan is good and pleasing and perfect.
I appeal to you therefore, brethren, and beg of you in view of [all] the mercies of God, to make a decisive dedication of your bodies [presenting all your members and faculties] as a living sacrifice, holy (devoted, consecrated) and well pleasing to God, which is your reasonable (rational, intelligent) service and spiritual worship. Do not be conformed to this world (this age), [fashioned after and ada pted to its external, superficial customs], but be transformed (changed) by the [entire] renewal of your mind [by its new ideals and its new attitude], so that you may prove [for yourselves] what is the good and acceptable and perfect will of God, even the thing which is good and acceptable and perfect [in His sight for you].
