1 Corinthians 12:14-19

Yes, the body has many different parts, not just one part. If the foot says, “I am not a part of the body because I am not a hand,” that does not make it any less a part of the body. And if the ear says, “I am not part of the body because I am not an eye,” would that make it any less a part of the body? If the whole body were an eye, how would you hear? Or if your whole body were an ear, how would you smell anything? But our bodies have many parts, and God has put each part just where he wants it. How strange a body would be if it had only one part!
