Why are you uncomfortable with the supernaturalist worldview of the biblical writers? Evangelicals don't want to just say, "Well, the inspired writers were wrong about some of their beliefs about the spiritual world and its inhabitants." That really doesn't work in a confessional situation! So instead we come up with excuses and interpretations that allow us to remake the biblical writers in our own post-Enlightenment image. I understand that impulse, but it's not honest.
