Romans 12:3-5

3For, through the grace given to me, I say, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith.1

4For as we have many members in one body, and all members have not the same office:

5So we, being many, are one body in Christ, and every one members one of another.
