1 Corinthians 12:14-17

In fact, the human body is not one single part but rather many parts mingled into one. So if the foot were to say, “Since I’m not a hand, I’m not a part of the body,” it’s forgetting that it is still a vital part of the body. And if the ear were to say, “Since I’m not an eye, I’m not really a part of the body,” it’s forgetting that it is still an important part of the body. Think of it this way. If the whole body were just an eyeball, how could it hear sounds? And if the whole body were just an ear, how could it smell different fragrances?
