The possessions God allows us to have are intended for our use, not our enjoyment. Trying to squeeze something out of them that was never in them in the first place is a futile endeavor. A cow's udders, gently pressed, will yield sweet milk, nourishing and refreshing. Applying more and more pressure will not produce greater quantities of milk. We lose the good of material things by expecting too much from them. Those who try hardest to please themselves with earthly goods find the least satisfaction in them.
