Who, when he came, and had seen the grace of God, was glad, and exhorted them all…
At the oceanside, where cliffs jut out to the waves, certain molluscs may be found sticking tightly to the rocks. Each mollusc clings so tenaciously that the concussion of the waves cannot smite it off. The secret of its hold is that the mollusc is empty. If it were filled either with flesh or with air, it would drop off immediately. This beautifully illustrates the condition of every sincere, humble, conscientious believer, who has been emptied of self, and therefore clings, by a Divine law of adhesion, closely to the Rock of Ages. If he should become puffed with pride and self-conceit, or gorged with fleshly indulgence, he would yield to the waves of temptation and be swept away.
