The trials of life are God’s workmen, to remove the impurities and roughness from our characters. Their hewing, squaring, and chiseling, their burnishing and polishing, is a painful process, it is hard to be pressed down to the grinding wheel. But the stone is brought forth prepared to fill its place in the heavenly temple. Upon no useless material does the Master bestow such careful, thorough work. Only His precious stones are polished after the similitude of a palace.
