God has hidden every precious thing in such a way that it is a reward to the diligent, a prize to the earnest, but a disappointment to the slothful soul. All nature is arrayed against the lounger and the idler. The nut is hidden in its thorny case; the pearl is buried beneath the ocean waves; the gold is imprisoned in the rocky bosom of the mountains; the gem is found only after you crush the rock which encloses it; the very soil gives its harvest as a reward to the laboring farmer. So truth and God must be earnestly sought.
