Lord, You can...so will You?

"Sometime later, Ben-Hadad, king of Aram mobilized his entire army and marched up and laid siege to Samaria. There was a great famine in the city; the siege lasted so long that a donkey's head sold for a eighty shekels of silver, and a quarter of a cab of seed pods for five shekels....Elisha said, 'Hear the word of the LORD. This is what the LORD says: About this time tomorrow, a seah of flower will sell for a shekel and two seahs of barley for a shekel at the gate of Samaria.'
The officer on whose arm the king was leaning said to the man of God, 'Look, even if the LORD should open the floodgates of the heavens, could this happen?'
'You will see it with your own eyes,' answered Elisha, 'but you will not eat any of it!'...
So the messengers returned and reported to the king. Then the people went out and plundered the camp of the Arameans. So, a seah of flour sold for a shekel, and two seahs of barley sold for a shekel, as the LORD had said."
(II Kings 6:24-7:20)

Lord I know that this is a story of how you worked one time, not a promise to do it again. But could you do it this time? Please?
