This is not a literal war; this is a symbolic war. This is not a future war; Christ is waging this war right now. I know Christ is waging this war right now because I am among those who have been slain by the sword of his mouth and raised again to newness of life! Jesus slays me. He slays me with his divine word. And in slaying me, he sets me free. This is salvation. John the Revelator is showing us how Jesus saves the world.
