Romans 12:1-2

1Therefore 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.

2Do 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.
