Every army that has ever existed has dreamed of having a secret weapon – some kind of unknown and previously unavailable source of power over their enemies. In World War I, the airplane proved to be a new weapon in the arsenal of both sides in the conflict. In World War II, Hitler believed he had the war won because of the development of another aviation innovation: The jet fighter. But in Joshua 11:1-19, we are going to see Joshua and his forces outnumbered and outmanned by superior enemy armies. They are going to lack the kind of sophisticated weaponry fielded by the opposite side. But Joshua was learning to recognize that their greatest source of strength and power was not going to come in the form of chariots or the latest, state-of-the-art weapons systems. It was going to come from God Himself. He was their secret weapon – a power so great that no army in existence could stand before Him. He was learning the truth behind the statement penned centuries later by the apostle Paul: If God is for us, who can ever be against us?
