The problem with the idea of NO MORE WAR is that such an idea doesn't exist. Even if there was peace all around the world, with no nation at all fighting against any other nation, people would still die of old age. And that is the biggest war of all, because God wanted people to live forever. Nobody can turn against God. Rather, any person who attempts to do so, really turns against himself, and ultimately dies. The wars that are between nations help to wake people up to the real war that many of us attempt against God. So, wars can be a good thing, because they will drive some of the people to God so that they are saved. In other words, wars between nations wake people up to the reality of God and the BIG death war.
