What a foolish man the builder of the house shown in our picture must have been! Of course, when the wind blew and the waves dashed against his house, it would fall. Look how the sea has washed the foundation away, and how the roof is falling in! And the people; see how they are fleeing to save their lives! And all this calamity because he built his house upon the sand. But the other house, shown in the distance: how firmly that stands! What a bold front it offers to the waves, and how safely it resists the fury of the storm. Its foundations are sure, because they rest upon the solid rock.
