The priest of dwindling parish that is perpetually cash-strapped can no longer overlook the shabby appearance of the church, whose interior walls badly need a new coat of color. He scrapes up a bit of money and purchases what he hopes will be gallons enough to do the job. Halfway through the exercise, he sees that he has miscalculated, but he recalls from a few days ago that he had seen several tins of paint thinner in the basement, which he retrieves. He extends the primary material and at last covers the final wall. It does no good. As the new layer dries the crummy-looking old layer shows through with a vengeance, even uglier than before.
At this moment a voice comes booming out of heaven: “Repaint, repaint,” it says, “and thin no more!”
