"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.' No, much rather, those members of the body which seem to be weaker are necessary." (1 Cor. 12:20-22)

One day it occurred to the members of the body that they were doing all the work and that the belly was having all the food. So they held a meeting and after a long discussion decided to strike work until the belly consented to take its proper share of the work. So for a day or two the hands refused to take the food, the mouth refused to receive it, and the teeth had no work to do. But after a day or two, members began to find that they themselves were not in very active condition. The hands could hardly move, the mouth was all parched and dry, while the legs were unable to support the rest. Thus, they found that even the belly, in its dull quiet way, was doing necessary work for the body, and that all must work together or the body would go to pieces. (From Aesop)
