Since there is much discussion about the war against the Canaanites, I thought I would add something else. A few years ago, Clay Jones wrote an article for the journal Philosophia Christi on this topic. You can read the article online here.
Disclaimer: I am NOT saying that this article demolishes every concern about what happened to the Canaanites. It simply adds some context to the issue so that we can (hopefully) have more intelligent discussion beyond “God is my BFF” or “God is a jerk.” Everyone understand?
