Where there are no demons, we demonize. And without a clear vision of the concrete forces we as the church are supposed to be aligned against, we find it very difficult to differentiate between enemy combatants and their hostages.
The Scriptures command us to be gentle and kind to unbelievers, not because we are not at war, but because we're not at war with them (2 Tim. 2:26). When we see that we are warring against principalities and powers in the heavenly places, we can see that we're not wrestling against flesh and blood (Eph. 6:12). The path to peace isn't through bellicosity or surrender, but through fighting the right war (Rom. 16:20).
