“Spiritual warfare” is currently popular among many christian groups, especially those that are more charismatically oriented. Apparently Jesus didn’t do a good enough job of “disarming the rulers and authorities, making a public display of them, and triumphing over them” (Colossians 2:15) and we need to give him a hand and beat up some demons.
Jesus brought an end to all spiritual warfare. So enjoy yourself a joyfare instead.
