And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels, And prevailed not; neither was their place found any more in heaven. And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him. Revelation 12:7-9
I do not think the war in heaven was fought with machine guns and army tanks. I believe it was a war of the minds. Satan, who was full of himself was trying to create and ego in the other angels as well. I don’t know, but I can imagine him coming up to another angel and saying, “That was a wonderful job you did on that project God gave you. Did He give you any special recognition for it?” The other angel replies, “Well no, I did not really need any….” Satan interrupts, “Oh that is too bad. You did such a wonderful job. You know, if I was God I would have thrown a huge banquet in your honor.” And thus, Satan began the war of the minds, attempting to make the angels think he cared more about them than God.
God could have eliminated Satan right then and there, but if He had, we would be serving God for fear of being wiped out too, instead of out of love. God had to allow Satan to grow into the weed that he is so that all could see later, why Satan had to be eliminated.
In the Lord’s prayer we pray, “Thy will be done on earth as it is in heaven.” In heaven Satan was cast out along with all his lies. When we pray “thy will be done on earth as it is in heaven,” we are giving Michael permission to throw Satan and all his lies out of our hearts, homes, churches and even communities. If God can cast Satan out of heaven He can also cast Him out of your heart and home!
