War end in Peace then why you start War why dont you start in Peace and rest in Peace?

There was a war in heaven before we came to this earth, and Satan who was cast out of heaven has encouraged man to make war not only against God but also against themselves. War brings out the worst, and sometimes the good in mankind. Man is what is known as carnal by nature and is therefore warlike. War will never cease upon this earth until the Savior comes and banishes all of the wicked. We live in an imperfect world and there will always be men who find joy in war, mostly for their own gain. You could also say peace ends in war why not start with war and continue in war sooner or later you will rest in peace
