12:1 Therefore I exhort you, brothers and sisters, by the mercies of God, to present your bodies as a sacrifice ? alive, holy, and pleasing to God ? which is your reasonable service. 12:2 Do not be conformed to this present world, but be transformed by the renewing of your mind, so that you may test and approve what is the will of God ? what is good and well-pleasing and perfect.

Romans 12:1-2
