Socrates once said, "An unexamined life is not worth living." In Power Through Truth: Practical Applications for Your Life, Louis Van Greninger encourages the reader to examine his or her own life fully. He distills thirty-seven years of study and research into a philosophy of life to bring the reader to a new level of awareness and to help all navigate the sometimes-rough waters of a material world. Greninger's book explores the physical, spiritual, and mental facets of everyday life. Through positive thinking and the application of Christian principles, he guides the reader to a better understanding of what it means to be human. The author also provides practical advice-whether it be improving health, buying a car, or choosing a spouse. The goal of the book can be found in the title-empowering the reader to live a more fulfilling life through Christian truths and belief in self.
