The sea was raging, the bark wherein the disciples were sailing was being tossed; but Christ was sleeping: at length it was seen by them that among them was sleeping the Ruler and Creator of winds; they drew near and awoke Christ; He commanded the winds, and there was a great calm. With reason then perchance your heart is troubled, because you have forgotten Him on whom you have believed: beyond endurance you are suffering, because it has not come into your mind what for you Christ has borne. If unto your mind comes not Christ, He sleeps: awake Christ, recall faith. For then in you Christ is sleeping, if you have forgotten the sufferings of Christ: then in you Christ is watching, if you have remembered the sufferings of Christ.
