Romans 12:3-5

For I say, through the grace given unto me, 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. {soberly: Gr. to sobriety} For as we have many members in one body, and all members have not the same office: So we, {being} many, are one body in Christ, and every one members one of another.
