Hear yet another consideration. Ever adversity and affliction, if not accompanied by patience, produces double torment; for a man’s patience casts off his distress, while faintness of heart is the mother of anguish. Patience is the mother of consolation and is a certain strength which is usually born of largeness of heart. It is hard for a man to find this strength in his tribulations without a gift from God, received through his ardent pursuit of prayer and the outpouring of tears.
