In this passage, God reminds Judah its supposed power during its recent encounter with the Assyrians was not what saw them through. Instead, it was God’s wisdom and power, requested by King Hezekiah who became humbled when faced with the prospect of losing his kingdom.
God reminded his people he is the creator. We need to remember this, too. It isn’t the thinking of man who brought about the creation of the world. It was the wisdom and power of God. Pitiful man will never sit in the seat of Creator God, though man wants to sit there very much.
Who gives God instruction? Not man. It is not within man to direct his steps (Jeremiah 10:23). Left to its own wisdom and devices, Judah would have made an ineffective alliance with Egypt, who had no intention of facing the Assyrians in Jerusalem!
God says, “Look, the nations are like a drop in a bucket; they are regarded as dust on the scales, (Isaiah 40:15 NET). The nations that worried Judah so were nothing. They were an insignificant threat from God’s perspective. We should remember God’s perspective and make it our own.
