Romans 12:3-8

For I say, through the grace that was given me, to every man that is among you, not to think of himself more highly than he ought to think; but so to think as to think soberly, according as God hath dealt to each man a measure of faith. For even as we have many members in one body, and all the members have not the same office: so we, who are many, are one body in Christ, and severally members one of another. And having gifts differing according to the grace that was given to us, whether prophecy, let us prophesy according to the proportion of our faith; or ministry, let us give ourselves to our ministry; or he that teacheth, to his teaching; or he that exhorteth, to his exhorting: he that giveth, let him do it with liberality; he that ruleth, with diligence; he that showeth mercy, with cheerfulness.
