1 Corinthians 12:20

But now are they many members
Of different make and shape, in different parts and places, and of different use and service: yet but one body;
all are united together, and make up one complete body, and which without each of them would not be perfect: so there are many members in the body of Christ, the church; some are teachers, others are hearers; some give, and others receive; but all make up but one church, of which Christ is the head; nor can anyone of them be spared; was anyone wanting, even the meanest, there would be a deficiency, and the church would not be the fulness of him that filleth all in all.
