Strategic Level Spiritual Warfare
Some Christians believe they can determine which so-called Territorial Spirits are in charge of certain geographic areas.
This determination is made through an approach called Spiritual Mapping.
Once a map for a given area has been completed, it is used in so-called Strategic Level Spiritual Warfare (SLSW).
[C. Peter Wagner] defines three levels of spiritual warfare: “Ground-level” involves casting demons out of individuals; “occult-level warfare” involves more organized “powers of darkness” [They target here New Age thought, Tibetan Buddhism, Freemasonry, etc.]; and “strategic-level warfare” directly “confronts ‘territorial spirits’ assigned by Satan to coordinate activities over a geographical area.”
