“Behold, I send an angel before you to guard you on the way and to bring you to the place that I have prepared. Pay careful attention to him and obey his voice; do not rebel against him, for he will not pardon your transgression, for my name is in him.
“But if you carefully obey his voice and do all that I say, then I will be an enemy to your enemies and an adversary to your adversaries.
“When my angel goes before you and brings you to the Amorites and the Hittites and the Perizzites and the Canaanites, the Hivites and the Jebusites, and I blot them out, you shall not bow down to their gods nor serve them, nor do as they do, but you shall utterly overthrow them and break their pillars in pieces. You shall serve the LORD your God, and he will bless your bread and your water, and I will take sickness away from among you. None shall miscarry or be barren in your land; I will fulfill the number of your days. I will send my terror before you and will throw into confusion all the people against whom you shall come, and I will make all your enemies turn their backs to you. And I will send hornets before you, which shall drive out the Hivites, the Canaanites, and the Hittites from before you. I will not drive them out from before you in one year, lest the land become desolate and the wild beasts multiply against you. Little by little I will drive them out from before you, until you have increased and possess the land. And I will set your border from the Red Sea to the Sea of the Philistines, and from the wilderness to the Euphrates, for I will give the inhabitants of the land into your hand, and you shall drive them out before you. You shall make no covenant with them and their gods. They shall not dwell in your land, lest they make you sin against me; for if you serve their gods, it will surely be a snare to you.” (Exodus 23:20-33, ESV)
The word “angel” means “messenger” and Yahweh says here that this messenger who is going to accompany Israel and guard them on the way has His name, Yahweh, in him. The nation must be careful to obey this messenger and if they do they will have complete victory over all enemies. It is quite likely that this messenger is the Son, the pre-incarnate Jesus (before he took on human nature), the second person of the Trinity.
Yahweh promises that in Canaan, if Israel worships Him alone and makes no covenants with any in the land, that He will remove all their enemies and make them supernaturally prosperous, with no miscarriages, abundant supply of food, and eventually a homeland that stretches from the Red Sea that He miraculously enabled them to cross, to the Euphrates River in the north. Though Israel’s record of obedience will be quite spotty, in the day of Solomon Yahweh will nevertheless give Israel a time of prosperity much like this and land dimensions like this.
Yahweh also acknowledges the mutual dependence of the ecosystems He created and explains that He will not immediately drive out the current inhabitants lest the land get overrun with wild beasts. God is the ultimate ecologist.
There is so much God wants to do for us and so little we trust Him for. In our covenant with Him He has not promised perfect prosperity, despite the teachings of prosperity gospel preachers, but He has promised to use us to spread the kingdom message to the whole world and see the powers of the kingdom irrupting into this present age. He is not immediately bringing the kingdom but using us to “conquer” territory from the devil little by little. And there is always the need to maintain the conquered land. Where do you see idolatry rampant in your sphere of influence? What is your plan under God for taking it in His name? May we trust Him for our Canaan victories, our promised land.
