Instead, it is a dark day that Christians should avoid celebrating at all costs. In a reel posted to social media, ex-witch-turned-revivalist Jenny Weaver shared why Christians should not only avoid Halloween, but the specific danger behind the jack-o-lantern. With these demonic background origins, Weaver notes that the jack-o-lantern is irredeemable from being anything good because it is rooted in darkness. “You cannot redeem it,” says Weaver. She is the author of the upcoming book, The Power of Suddenly: Discover How God Can Change Everything in a Moment.
