Nothing so moves a sinner to repentance as eternity, and nothing is so useful to every Christian as remembrance and contemplation of eternity. Eternity restrains a man from sin, calms his passions, turns him from the world and all its vanity, makes his heart contrite, gives birth to tears of repentance, incites him to prayer, and works true sighing of the heart. Contemplation and remembrance of eternity can correct even the most depraved man.
Contemplation of eternity filled dwellers of the desert, caves, mountains and clefts of the earth. By contemplating eternity the holy martyrs willed to endure torments rather than submit to the will of ungodly kings and deny Christ.
