1 Corinthians 12:17-21

If the whole body were an eye, where were the hearing? If the whole were hearing, where were the smelling?

But now hath God set the members every one of them in the body, as it hath pleased him.

And if they were all one member, where were the body?

But now are they many members, yet but one body.

And the eye cannot say unto the hand, I have no need of thee: nor again the head to the feet, I have no need of you.
