Deuteronomy is the “go to” book for theocracy because it’s the most clear about the importance of the law and its application in the promised land where Israel would no longer be guided by the pillars of cloud and fire nor miraculously provided for by manna and water out of a rock.

Wilderness season is ending, so the emphasis of the law will shift to governing a people within their own country instead of as a nomadic people in the wilderness. This is extremely helpful for the church today.
