Yoga. Martial arts. Halloween. Horoscopes. Secret societies. The practices are everywhere — and the church cannot agree on which ones matter and which ones don’t. The Devil’s Playground, Book 3 of the Demonology Study Series, takes up the practices and the hard questions one at a time. The deep dives continue the numbering of Book 2’s, running from nine to sixteen — because these are not a new subject, only the same enemy met in daily life instead of in ancient texts.

It starts with a counting question: how many types of angels does Scripture actually describe — when only one angel in the entire Bible is ever called an archangel, and Daniel calls that same Michael “one of the chief princes,” a phrase the dive refuses to smooth over? Then Halloween, where the load-bearing claim of the viral warnings — that October 31 is the highest satanic holy day — is audited against the history, the testimony, and the text. Then the zodiac and astrology; secret societies and whether they are demonic; whether objects can carry evil spirits; yoga, examined as exercise, worship, or open door; and martial arts under the same three-way question — a chapter the author writes from the inside, as a man who once trained in iaido and aikido and laid the sword down. The final dive asks whether a demon’s name must be known to cast it out, and what the New Testament actually shows being said to demons.

Each practice is judged fairly, which means hearing its own voice first — its history, and what its own teachers say it is — before the Bible is asked to speak to it. The book also faces the questions believers ask behind closed doors: can a Christian be demon-possessed, what is deliverance biblically, how do you test a spirit, and what do you do when someone you love is involved in the occult? These are handled the same way as the practices — deliverance defined from the text rather than from the deliverance circuit’s habits, spirits tested by the tests Scripture itself gives, and the occult treated as a real door without turning every jack-o’-lantern into one. No fear-mongering, and no dismissing real concerns either. Fear is not the point and never was; the point is knowledge — “And ye shall know the truth, and the truth shall make you free” (John 8:32, KJV). Read it, and you will be able to sort the doors that are genuinely open from the alarms that are false — by the text, not by panic, and not by tradition either.
