We recommend “The Way of the Warrior: An Ancient Path to Inner Peace” by Erwin Raphael McManus. Its blurb is as follows:
Best-selling author, pastor, futurist, and cultural thought leader believes that to experience and establish peace, we must first confront the battles that rage within. McManus shows that encountering peace does not occur by accident, but rather by artful intention. Warrior is a call to decisiveness, self-examination, and the pursuit of spiritual wholeness. Through the ancient biblical practices of humility, focus, ownership, clarity, strength, and vulnerability, he guides readers to a deeper understanding of their inner workings and provides the guidance they need to establish peace and tranquility in their homes, neighborhoods, communities, and even the world! In the style of a battle-wizened teacher, McManus delivers wisdom, in stills passion, and provides the sacred movements needed to become the warrior you were meant to be.
