You alone are God over all the kingdoms of the earth

 2 Kings 19:1-19

When King Hezekiah heard this, he tore his clothes and put on sackcloth and went into the temple of the Lord. He sent Eliakim the palace administrator, Shebna the secretary and the leading priests, all wearing sackcloth, to the prophet Isaiah son of Amoz.

When King Hezekiah’s officials came to Isaiah, Isaiah said to them, “Tell your master, ‘This is what the Lord says: Do not be afraid of what you have heard—those words with which the underlings of the king of Assyria have blasphemed me. Listen! When he hears a certain report, I will make him want to return to his own country, and there I will have him cut down with the sword.’

Hezekiah received the letter from the messengers and read it. Then he went up to the temple of the Lord and spread it out before the Lord. And Hezekiah prayed to the Lord: “Lord, the God of Israel, enthroned between the cherubim, you alone are God over all the kingdoms of the earth. You have made heaven and earth. Give ear, Lord, and hear; open your eyes, Lord, and see; listen to the words Sennacherib has sent to ridicule the living God.

Now, Lord our God, deliver us from his hand, so that all the kingdoms of the earth may know that you alone, Lord, are God.”

Crisis brings out the best in Hezekiah. God answers his prayer and vindicates his trust. Isaiah's prophecy is fulfilled. Jerusalem is saved.

Why?

Field commander threatened King Hezekiah, and he went to the temple of the Lord, prayed to the Lord, and send officials to Isaiah to ask what to do. 

Hezekiah knew he is weak and can't fight his enemy, but his enemy shamed the Lord, so the Lord answered Hezekiah through the prophet Isaiah. The unbelievable result will be.

King Hezekiah heard the bad news he tore his clothes and went into the temple of the Lord... which shows Hezekiah is focused on the Lord, he believed only the Lord is his savior.

How?

Do I have the faith like Hezekiah, even in the worse situation still rely on the Lord?
