by Scott D. Hendricks
For as a gold refiner having cast a piece of gold into the furnace allows it to be proved by the fire until such a time as he sees it has become purer: even so God permits the souls of men to be tested by troubles until they become pure and transparent and have reaped much profit from this process of sifting; wherefore this is the greatest species of benefit.
~ St. John Chrysostom
