Luke 11:17-18
Jesus knew their thoughts and said to them: "Any kingdom divided against itself will be ruined, and a house divided against itself will fall. If Satan is divided against himself, how can his kingdom stand? I say this because you claim that I drive out demons by Beelzebub.
The Devil's kingdom will never stand because it will always be divided. The Devil and his demons are always fighting among themselves. They can never be united to do evil. That is the eternal curse they have earned from God. They boast in their unity to do evil on Earth, but they will end up fighting among themselves in greed and covetousness. You can never be untied to do evil on Earth. That has been the curse from the Tower of Babel in Genesis 11:1-11. The kingdom of darkness has never been united from then. They will pretend to be united for a while but their pride, arrogance, greed, covetousness,lust and evil desires will stand in their way. They will start destroying each other for good. The kingdom of darkness is meant for destruction. Remember, these are objects of God's wrath, prepared for eternal destruction. They may seem united but, they are not! They may seem powerful but, they are not! They may seem they are invincible, but they are not! They may seem they can never be shaken, but they will be shaken to the core and fall to the ground and be crushed. Pretense is their only defense, but how long? How long can they pretend? It will all fall apart miserably when their time comes. The kingdom of darkness is always fighting against God and His Christ. Just by the demonstration of power by God's Spirit they will all crumble down with shame and disgrace, that cannot be wiped away from their faces forever and ever!
Psalms 68:1-2
May God arise, may his enemies be scattered; may his foes flee before him. As smoke is blown away by the wind, may you blow them away; as wax melts before the fire, may the wicked perish before God.
