For in fact the body is not one member but many.
If the foot should say, “Because I am not a hand, I am not of the body,” is it therefore not of the body? And if the ear should say, “Because I am not an eye, I am not of the body,” is it therefore not of the body? If the whole body were an eye, where would be the hearing? If the whole were hearing, where would be the smelling? But now God has set the members, each one of them, in the body just as He pleased. And if they were all one member, where would the body be? But now indeed there are many members, yet one body.
I Corinthians 12:14~20
