Martin Luther once wrote to Erasmus, “Your thoughts about God are too human.”
Luther meant that we need to understand God’s love and justice according to God’s own revelation of himself in Scripture and not according to our own (fallen) ideas about what God’s love and justice ought to look like.
That’s a good reminder when we think about the whole issue of the conquest of the Canaanites. This is a large and difficult subject that requires humility and careful thought, but here are a few comments.
1. The conquest of the Canaanites was not “genocide.”
Genocide implies racial hatred. But when we read about God and Israel in the Old Testament, we discover a much different attitudes toward foreigners. Israel was chosen by God to be a blessing to the nations (Gen 12). Israel was called by God to show loving concern for strangers and aliens in their midst (Dt 10:18-19). God gave foreigners living in Israel the same rights that natives had (Lev 24:22). We could add other verses to the list, but it is clear that God did not endorse racism and xenophobia.
2. The conquest of the Canaanites was about sin, not race.
God did not give the land to the Israelites because of their race or superior righteousness. Deuteronomy 9:4-6 says “Because of the wickedness of these nations the Lord your God is driving them out from before you…” Canaanite idolatry made the land ripe for judgment. God is a divine warrior who takes sin seriously, but he is also gracious and his mercy was available to any Canaanite who turned to him in faith (i.e. Rahab). By the way, read the rest of the Bible and see that God is just as opposed to Israel’s idolatry as he was to the Canaanites.
3. The conquest of the Canaanites was a unique event.
The conquest was not a model for Israel’s relationship to the nations. Unlike the concept of jihad, the Bible presents the conquest as a unique salvation-historical event limited to a particular time and place (cf. Dt 20, which prohibits Israel from waging the same kind of warfare on enemies who are outside the land). The conquest foreshadows the final judgment when the wicked will have no inheritance in the new heavens and the new earth.
4. The conquest of the Canaanites uses hyperbolic language.
Upon first reading, you might get the impression that the Israelites killed every living thing and demolished every city. But language like “all,” “young and old,” “utterly destroyed,” “no survivors,” etc. is the rhetoric of warfare and contains hyperbole. So on the hand Joshua 10:40 says Joshua struck the whole land and left no one, but Judges 2:21 refers to all the nations which Joshua left when he died. This is not a contradiction; it is a recognition that sometimes the Bible uses language which shouldn’t be pressed too literally (like when I beat someone at cribbage by 3 points and exclaim with glee, “I trounced you!”). Keep in mind that in Dt 7:22 God said that Israel would take possession of the land gradually over time, “little by little” and “not all at once.”
5. The conquest of the Canaanites is part of the story that leads to the cross of Calvary.
There are many scriptures, such as Psalm 87 and Isaiah 19, that talk about God’s inclusion of the nations that opposed Israel. God’s ultimate plan is to bring all nations into the orbit of his salvation, not by bringing judgment but by bearing it in the cross of Christ for us. Here is a wonderful quotation from Chris Wright’s book, The God I Don’t Understand:
But at some point I have to stand back from my questions, criticism, or complaint and receive the Bible’s own word on the matter. What the Bible unequivocally tells me is that this was an act of God that took place within an overarching narrative through which the only hope for the world’s salvation was constituted.
Within that overall biblical perspective, the road to Canaan was one small stretch along the road to Calvary. From that point of view, I cannot do other than include it among the mighty acts of God for which all his people are called to praise him. I have to read the conquest in the light of the cross.
And when I do set it in that light of the cross, I see one more perspective. For the cross too involved the most horrific and evil human violence, which, at the same time, also constituted the outpouring of God’s judgment on human sin. The crucial difference, of course, is that whereas at the conquest, God pour out his judgment on a wicked society who deserved it, at the cross, God bore on himself the judgment of God on human wickedness, through the person of his own sinless Son – who deserved it not one bit.
…note once again that humble submission to the biblical teaching on the sovereignty of God on the one hand, along with robust reflection on the mystery of the cross of Christ on the other, combine to strengthen our faith in the midst of things we do not understand.
