1 Corinthians 12:14-17

And a person’s body has more than one part. It has many parts. The foot might say, “I am not a hand, so I don’t belong to the body.” But saying this would not stop the foot from being a part of the body. The ear might say, “I am not an eye, so I don’t belong to the body.” But saying this would not make the ear stop 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 anything.
