1 Corinthians 12:17-21

If the whole body were an eye, where would the hearing be? If the whole body were hearing, where would the sense of smell be?

But now God has arranged the parts, each one of them in the body, just as He desired.

If they were all one part, where would the body be?

But now there are many parts, but one body.

And the eye cannot say to the hand, “I have no need of you”; or again, the head to the feet, “I have no need of you.”
