15 If the foot were to say, "Because I am not the hand, I am not of the body," would it then not be of the body?
16 And if the ear were to say, "Because I am not the eye, I am not of the body," would it then not be of the body?
17 If the whole body were the eye, how would it hear? If the whole were hearing, how would it smell?
18 But instead, God has placed the parts, each one of them, in the body, just as it has pleased him.
19 So if they were all one part, how would it be a body?
20 But instead, there are many parts, indeed, yet one body.
21 And the eye cannot say to the hand, "I have no need for your works." And again, the head cannot say to the feet, "You are of no use to me."
