Romans 12:3-8 (NASB)

3 For through the grace given to me I say to everyone among you not to think more highly of himself than he ought to think; but to think so as to have sound judgment, as God has allotted to each a measure of faith.4 For just as we have many members in one body and all the members do not have the same function, 5 so we, who are many, are one body in Christ, and individually members one of another. 6 Since we have gifts that differ according to the grace given to us, each of us is to exercise them accordingly: if prophecy, according to the proportion of his faith;7 if service, in his serving; or he who teaches, in his teaching; 8 or he who exhorts, in his exhortation; he who gives, with liberality; he who leads, with diligence; he who shows mercy, with cheerfulness.
