Thought from Today's Old Testament Passage:
"And in that day thou shalt say, O Lord, I will praise Thee; though Thou wast angry with me, Thine anger is turned away, and Thou comfortedst me." —Isaiah xii. 1.
This prophecy is said by some to relate to the invasion by Sennacherib. That calamity threatened to be a very terrible display of divine anger. It seemed inevitable that the Assyrian power would make an utter desolation of all Judea; but God promised that He would interpose for the deliverance of His people, and punish the stout heart of the king of Assyria, and in that day His people would say, "We will praise Thee: though Thou wast angry with us, and therefore sent the Assyrian monarch to chastise us, Thine anger is turned away, and Thou comfortedst us." If this be the meaning of it, it is an instance of sanctified affliction, and it is a lesson to us that whenever we smart under the rod, we may look forward to the time when the rod shall be withdrawn; and it is also an admonition to us that when we escape from trial, we should take care to celebrate the event with grateful praise. Let us set up the pillar of memorial, let us pour the oil of gratitude upon it, and garland it with song, blessing the Lord whose anger endureth but for a moment, but whose mercy is from everlasting to everlasting.
