1 Corinthians 12:14-25

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? But now [as things really are], God has placed and arranged the parts in the body, each one of them, just as He willed and saw fit [with the best balance of function]. If they all were a single organ, where would [the rest of] the body be? But now [as things really are] there are many parts [different limbs and organs], but a single body. The eye cannot say to the hand, “I have no need of you,” nor again the head to the feet, “I have no need of you.” But quite the contrary, the parts of the body that seem to be weaker are [absolutely] necessary; and as for those parts of the body which we consider less honorable, these we treat with greater honor; and our less presentable parts are treated with greater modesty, while our more presentable parts do not require it. But God has combined the [whole] body, giving greater honor to that part which lacks it, so that there would be no division or discord in the body [that is, lack of adaptation of the parts to each other], but that the parts may have the same concern for one another.
