Gone are the flat-earth days of scientific rationalism. Humans, it turns out, are naturally hungry for mystery, magic, faith. There have been laments about disenchantment and calls for re-enchantment. Many who forsake traditional religion are drawn to spiritualism and pagan beliefs and practices. Christians, meanwhile, have always affirmed that there is more than meets our eyes, that our world is teeming with angels and demons, powers and principalities, signs and wonders. The "supernatural" is real; in fact, it's entirely natural. Whether you believe it or not, there are powers you should rightly fear, and one you should serve.
