Why does God afflict the best of men with ill-health, or sorrow, or other troubles? Because in the army the most hazardous services are assigned to the bravest soldiers: a general sends his choicest troops to attack the enemy in a midnight ambuscade, to reconnoitre his line of march, or to drive the hostile garrisons from their strong places. No one of these men says as he begins his march, "The general has dealt hardly with me," but "He has judged well of me.""
