As a practicing Christian, I think the Bible, where the teachings of my faith reside, defines the unseen reality behind evil as Satan along with the demons (or “angels” in some translations) who follow him. I know this sounds like the stuff of fairy tales, but I think a case can be made that the Bible’s teaching about Satan and the creation account of humankind’s fall in Genesis 3 is as viable an option as any that defines the source of evil in this world.
Most of what consumes mankind is invisible - politics, economics, trading value, religion. The thing sought can be made material, but the drive is invisible. Getting and giving, does it reflect worship in truth and spirit of the creative power of light, or the kingdom as a social structure on earth?
