There is, according to Scripture, no doubt that Satan rules over a hierarchy of evil spirits who inhabit the earth’s atmosphere and who assist him in ruling the kingdom of darkness. That those evil spirits are “territorial,” ruling over certain geographical areas, is a concept that is also contained in the Bible (see Dan. 10:13, 20-21; Mark 5:9-10). That Christians have the authority to cast demons out of other people and the responsibility to resist the devil is scriptural (see Mark 16:17; Jas. 4:7; 1 Pet. 5:8-9). But can Christians pull down evil spirits over cities? The answer is that they can’t, and to attempt to do so is a waste of their time.
Just because we can cast demons out of people, we should not assume that we can pull down evil spirits over cities. There are numerous examples of casting demons out of people in the Gospels and the book of Acts, but can you think of even one example in the Gospels or the book of Acts where someone pulled down an evil spirit that was ruling over a city or geographical area? You can’t because there are no such examples. Can you think of one instruction anywhere in the epistles about our responsibility to pull down evil spirits from the atmosphere? No, because there are none. For this reason, we have no biblical basis to believe that we can or should be waging “spiritual warfare” against evil spirits in the atmosphere.
