Like the Israelites marched around the walls of Jericho, and only when they lifted up their voices did the walls crumble down, we must speak the promises to achieve victory. Like Elijah called down fire on those who came to oppose him, we call down our 'fire' (miracle) with our voice. But just as Elijah, when we forget to speak, we flee defeated and in fear. Your voice speaking the Word is the weapon to reinforce your victory.
