Book excerpt: A best-selling author, pastor, futurist, and cultural thought leader argues that to experience and establish inner peace, we must first confront the battles that rage within. Your longings for inner peace and deep purpose are attainable, but they won't come easy. They require a warrior's mentality. Fighting for them requires passion, perseverance, and precision. This is an invitation to an unflinchingly honest look at your interior life guided by the ancient principles and methods revealed through Scripture. Erwin Raphael McManus delivers wisdom, instills passion, and provides the sacred movements needed to become the warrior you were meant to be. We live in a time of global and personal chaos. The world is at war because our souls are at war. The path to peace begins with you overcoming your most frequent and fierce enemy: yourself.
