1 Corinthians 12:14-17

For the [human] body does not consist of one part, but of many [limbs and organs]. If the foot says, “Because I am not a hand, I am not a part of the body,” is it not on the contrary still a part of the body? If the ear says, “Because I am not an eye, I am not a part of the body,” is it not on the contrary still a part of the body? If the whole body were an eye, where would the hearing be? If the whole [body] were an ear, where would the sense of smell be?
