Romans 12:1-5

I urge you therefore, brothers, by the mercies of God, that you present your bodies as a living sacrifice, holy, and acceptable to God, which is your reasonable service of worship. Do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is the good and acceptable and perfect will of God. For I say, through the grace given to me, to everyone among you, not to think of himself more highly than he ought to think, but to think with sound judgment, according to the measure of faith God has distributed to every man. For just as we have many parts in one body, and not all parts have the same function, so we, being many, are one body in Christ, and all are parts of one another.
