Isaiah ministered and wrote to the people of Jerusalem and Judah. His task was to explain to these chosen people that the old world order was passing away and that the new order, controlled by Gentile world empires that sought to swallow Judah up, required a new commitment to trust and obey Yahweh as His servant. The Assyrian threat called for this new dedication. This was a theological even more than a historical and political crisis for Judah. It raised many questions that Isaiah addressed.
"Is God truly the Sovereign of history if the godless nations are stronger than God's nation? Does might make right? What is the role of God's people in the world? Does divine judgment mean divine rejection? What is the nature of trust? What is the future of the Davidic monarchy? Are not the idols stronger than God and therefore superior to him?"13
The far-reaching nature of these questions called for reference to the future, which Isaiah revealed from the Lord. The Northern Kingdom had made the wrong commitment, which Amos announced, but the Southern Kingdom still had an opportunity to trust Yahweh and live.
"Stated briefly, the purpose of Isaiah is to display God's glory and holiness through His judgment of sin and His deliverance and blessing of a righteous remnant."14
