The notion that spiritual warfare involves direct confrontation with demons is foreign to Scripture. Christians who verbally confront demons waste energy and demonstrate ignorance of the real war. We are not called to convert demons, but sinners. The battle is rather with the false ideologies men and demons propagate so that the world believes them. Doomed souls are inside their fortresses of ideas, which become their prisons and eventually their tombs – unless they are delivered from them by belief in the truth.
