According to the book He Came to set the Captives free by Dr Rebecca Brown, Satan’s army is vast and extremely organized. According to what she saw in the occult, there are demon generals and troops over countries, states, counties, cities, down to each family they are assigned to, to try and infiltrate and corrupt. This is indeed why we need to put on our spiritual armor of God each day because “our advisory, the devil, roams to and fro, seeking whom he may devour”.
