Romans 12:1-5

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. 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. For by the grace given to me I say to every one of you not to think more highly of yourself than you ought to think, but to think with sober discernment, as God has distributed to each of you a measure of faith. For just as in one body we have many members, and not all the members serve the same function, so we who are many are one body in Christ, and individually we are members who belong to one another.
