1 Corinthians 12:14-20

The human body has many parts. The foot might say, “Because I am not a hand, I am not part of the body.” But saying this would not stop the foot from being a part of the body. The ear might say, “Because I am not an eye, I am not part of the body.” But saying this would not stop the ear from being a part of the body. If the whole body were an eye, it would not be able to hear. If the whole body were an ear, it would not be able to smell. If each part of the body were the same part, there would be no body. But truly God put all the parts, each one of them, in the body as he wanted them. So then there are many parts, but only one body.
