Nineveh, which is the capital of Assyria, was the greatest city the world had yet seen. It was an impregnable fortress. Military might, economic might, cultural might …
Nobody in their right mind would even think of besieging the city, let alone trying to capture the city, because you couldn’t even get an army around it. Who had an army that could stretch around the circumference of this city? But the foolishness of God is wiser than the wisdom of men, and God decides, not just to besiege the city, but to sack it with an army of one.

God did it by taking one person (one man, in this case) and turning that one man into a city-changer, into a world-changer. Then, by doing so, he was able to sack the greatest city in the history of the world up to that time. How did God make Jonah an Army of one? There are four things that we learn: God’s persistent grace makes you an army of one; God’s calling makes you an army of one, God’s strategy, and God’s power.
