Satan is real—a powerful spiritual being, the third player in the Story along with God and man. He has invaded God’s Kingdom of light to bring his own kingdom of darkness. He gains ground by craftiness and secrecy, and he destroys by lies, accusation, enticement, and subterfuge. If you doubt him, beware. Stealth is his weapon. Satan happily stays in the shadows where he can do his dark business undetected. Underestimate him—or worse, ignore him—to your peril.
