1 Corinthians 12:12-21

For just as the body is one and has many parts, and all the parts of that body, though many, are one body — so also is Christ. For we were all baptized by one Spirit into one body — whether Jews or Greeks, whether slaves or free — and we were all given one Spirit to drink. Indeed, the body is not one part but many. If the foot should say, “Because I’m not a hand, I don’t belong to the body,” it is not for that reason any less a part of the body. And if the ear should say, “Because I’m not an eye, I don’t belong to the body,” it is not for that reason any less 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 as it is, God has arranged each one of the parts in the body just as he wanted. And if they were all the same part, where would the body be? As it is, there are many parts, but one body. The eye cannot say to the hand, “I don’t need you!” Or again, the head can’t say to the feet, “I don’t need you!”
