The leaders of Judah, speaking for their king, acknowledged that he had come to the end of his rope. The Assyrian invasion of Judah had been like labor pains for the king, but now the crisis had peaked and there was no human strength left to expel the enemy. Hezekiah confessed that he deserved the adversity that had overtaken him, which had signaled an end of hope and resulted in great embarrassment. Yet he did not appeal for divine help on the basis of his own needs but because of the Lord"s honor and the needs of His people (cf. 1 Samuel 17:26; 1 Samuel 17:36). The king appealed for Isaiah"s prayers on behalf of the remnant, the remaining Judahites who had not already been devoured by the Assyrians. [source][source][source]
"This kind of admission of helplessness is frequently a necessity before divine help can be received. So long as we believe that we only need some assistance, we are still treating ourselves as lords of the situation, and that latent pride cuts us off from all that God would give us." [1][source]
The saying "God is my copilot" may reflect a similar attitude. [source][source][source]
