Whether they come from within us or outside us, whether they represent distinct personalities or the sins and systems that compete for our allegiance, demons are as real as the competing identities that seek to possess us. But rather than casting them out of our churches, we tend to invite them in, where they tell us we’ll be children of God when . . . we beat the addiction. we sign the doctrinal statement. we help with the children’s ministry. we get our act together. we tithe. we play by the rules. we believe without doubt. we are married. we are straight. we are religious. we are good.
