Then war broke out in heaven. Michael and his angels fought against the dragon, and the dragon and his angels fought back. But he was not strong enough, and they lost their place in heaven. The great dragon was hurled down—that ancient serpent called the devil, or Satan, who leads the whole world astray. He was hurled to the earth, and his angels with him…
Then the dragon was enraged at the woman and went off to wage war against the rest of her offspring—those who keep God’s commands and hold fast their testimony about Jesus.Revelation 12:7-9, 17
Satan was cast out of heaven. But where did he go? He now creates havoc on the earth. That is why he is called the “prince of this world” (John 12:31; 14:30; 16:11). And with him came 1/3 of the angels (according to Revelation 12:4) who now operate under Satan’s command and control structure–not unlike the mafia. Paul calls the different levels of demonic entities “the rulers… the authorities… the powers of this dark world and… the spiritual forces of evil in the heavenly realms“(Ephesians 6:12).
Just as the different angels had different roles and different levels of power and strength in heaven, when they were cast down to the earth, they retained a measure of that same hierarchy. Only now, out of fear, they answer to Satan–the former archangel.
So there are principalities of darkness that operate over entire geographical regions (see Daniel 10:13). These beings have retained more of their angelic presence and can deceptively appear as an angel of light (2 Corinthians 11:14). They also don’t seem to need to dwell inside people. They seem to have retained more of their spiritual bodies after their fall from heaven. People with spiritual discernment can even feel the shift when you drive through different regions of our own country. Different principalities operate in different regions and over different cities.
There are powers that operate under these principalities who are strong but are clearly evil. These powers retain more of an identity as their names are personal names. They often retain the name of a pagan god or an evil character from the Bible. I’ve personally cast out ones named Jezebel, Baal, Thor, Hades, Hermes, etc.
While they have some power and can be harder to cast out than lower level demons, they don’t have any authority (see Matthew 28:18). So they are constantly trying to usurp and steal a person’s own authority. The main way these powers try to get into someone’s life is through chronic sin (including unforgiveness), trauma, and using deception. They try to get the person to agree to the lies they are whispering in their ear. Once the person agrees with the lies, the door is opened.
Finally, there are demons in operation under the powers. Demons are weaker and need a “host” to cling to (Matthew 12:42; Luke 11:24). They don’t have much power or much of an identity. Their name tends to be what sin they try to tempt their host to do. So they tend to be named spirit of anger, spirit of hate, spirit of lust, spirit of death, spirit of suicide, spirit of despair, spirit of perversion, spirit of pride, spirit of doubt, spirit of unbelief, spirit of addiction, etc.
Like a gang or the mafia, the lower level spiritual forces of evil answer to higher level ones. And like a gang or the mafia they only work together for selfish reasons. They actually hate each other and are in constant competition with each other. Submission to the demonic entity above them doesn’t happen out of honor or love but out of the fear of pain and punishment.
While spiritual forces of evil hate each other, they hate humanity even more because we are created in the image of God. We remind them of all that they lost in their fall from heaven. They especially hate Christians because of the Spirit dwelling in us and our position as sons and daughters in the Kingdom of God. We are the royal heirs of the Kingdom they lost. Because of this, the kingdom of darkness wages war against all followers of Jesus everywhere around the globe.
If you are a Christian, you are in a war. It’s raging all around you. Ignoring it doesn’t make it go away. Pick up your weapons and your armor and fight (Ephesians 6:10-20), or you will be just another casualty of war!
