1 Corinthians 12:21-27

And the eye cannot say to the hand, I have no need of thee: or again the head to the feet, I have no need of you. Nay, much rather, those members of the body which seem to be more feeble are necessary: and those parts of the body, which we think to be less honorable, upon these we bestow more abundant honor; and our uncomely parts have more abundant comeliness; whereas our comely parts have no need: but God tempered the body together, giving more abundant honor to that part which lacked; that there should be no schism in the body; but that the members should have the same care one for another. And whether one member suffereth, all the members suffer with it; or one member is honored, all the members rejoice with it. Now ye are the body of Christ, and severally members thereof.
