Isaiah With Training Wheels: Ch. 36-37
Here, we are closing out the first section of Isaiah. The emphasis has been on Temporal Salvation, and the Messiah as the King of Jerusalem and all Israel. The primary antagonist and geo-political foe, was Assyria, even as the Prophet rebukes the Lord’s own people. But here we are at the end. The wicked have been destroyed, or carried away, and the Assyrian armies advance on Jerusalem itself.
But in spite of the fact the Lord called Assyria to punish the wicked, the Lord Jehovah, Jesus Christ, is the King of Jerusalem. And when Sennacherib challenges the Jerusalem, the Lord shows that he, indeed, is the actual king. Thus, this historical interlude is not placed at random. It is the capstone and the historical realization of everything before it. It is the Lord demonstrating his divine patience and ultimately, his power.
