1 Corinthians 12:14-16

14Even so the body is not made up of one part but of many. 15Now if the foot should say, “Because I am not a hand, I do not belong to the body,” it would not for that reason stop being part of the body. 16And if the ear should say, “Because I am not an eye, I do not belong to the body,” it would not for that reason stop being part of the body.
