Romans 12:3-5

3For 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.

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

5so we, who are many, are one body in Christ, and severally members one of another.
