As in other warfare worldviews, the Bible assumes that the course of this warfare greatly affects life on earth. Now, the very prevalence of the warfare worldview among so many different people-groups, in such radically different times and unrelated locations, should itself be enough to inspire us to take this worldview seriously. It is just possible that the intensely materialistic and rationalistic orientation of the Enlightenment has blinded us to certain otherwise obvious realities. But even if the nearly universal intuition of cosmic conflict is not enough to call our own naturalism into question, the fact that this warfare worldview constitutes a central component of Scripture's understanding of God and the cosmos should surely inspire us to do so. At least for those of us for whom this collection of canonical books is no mere collection but rather constitutes the inspired Word of God, not seriously considering the warfare worldview can hardly be said to be an option, however much such a view may conflict with our own naturalistic cultural presuppositions.
Myth anticipates reality.
Indeed, I would go still further and argue that, if we consider the variety of warfare worldviews throughout the world and throughout history from a perspective that is thoroughly committed to Scripture, the most plausible way of understanding them is to see them as approximating and anticipating the truth revealed in Scripture. If we arrive at a full appreciation of just how thoroughly a warfare perspective is woven into the fabric of Scripture, all the pagan warfare perspectives present themselves as intuitive confirmations of the truth revealed in Scripture. In Scripture, and especially in the person of Jesus Christ, myth becomes reality, as C. S. Lewis insightfully put it. In this light, the nearly universal myth of our world being largely shaped by warfare among various cosmic forces and spirits is here incarnated as the one true God-man warrior of God enters our real war zone and wages war against God's real foes. God wages war against these forces, however, and through the person of Jesus Christ has now secured the overthrow of this evil cosmic army.
