I Corinthians 12:12-21

For as the body is one and has many members, but all the members of that one body, being many, are one body, so also is Christ. For by one Spirit we were all baptized into one body—whether Jews or Greeks, whether slaves or free—and have all been made to drink into one Spirit. 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. And the eye cannot say to the hand, “I have no need of you”; nor again the head to the feet, “I have no need of you.”
