Revelation 12:9 And the great dragon was cast out, that old serpent called the Devil, and Satan, which deceives the whole world: he was cast out into the earth, and his angels were cast out with him.
War began in heaven, and it will take Someone from heaven to stop wars, and that Person is Jesus Christ. From time to time well intentioned persons might have arisen, claiming to have the know how to stop world conflicts. But much to their chagrin, other battles flared up elsewhere and some found themselves putting out one fire when ten more were started. Even satan, in his appeal to the heavenly angels, proposed to bring in a better order of things, but again, he also failed miserably.
The reason for this is that peace and tranquility are products that originated with God, and therefore, if efforts are made, outside of the principles and laws of God, to bring wars to an end, all such efforts are bound to fail. In other words, no Jesus, no peace. Therefore, it is both a no brainer and a non-starter in one, for if one tries to bring about peace, while at the same time indulging in oppression, wickedness, fraud, lies, injustice and cruelty, peace will remain a figment of your imagination.
In other words, satan must never be given a seat at the negotiating table, whenever it comes to making peace because the very principles of his kingdom go directly contrary to the work of righteousness, and therefore, in a nutshell, not happening. Revelation 12: 7 And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels, 8 And prevailed not; neither was their place found any more in heaven.
Revelation 12:10 And I heard a loud voice saying in heaven, now is come salvation, and strength, and the kingdom of our God and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God, day and night.
May The Lord add His blessing to the study of His word. God bless!
