Francis Schaeffer was one of the most influential apologists of the twentieth-century. Through his speaking, writing, and filmmaking, Schaeffer successfully transformed the way people thought of the Christian faith, from a rather private kind of piety to a worldview that addresses every sphere of life. This volume—written by a man converted from agnosticism on the first day he met Schaeffer—is the first book devoted to exploring the heart and soul of Schaeffer’s approach to the Christian life. William Edgar sets Schaeffer’s views in historical context, articulates his core teachings, and explores the most significant implications of Schaeffer’s works. As the newest edition to the Theologians on the Christian Life series, this volume helps readers strive after the same kind of marriage of thought and life, of orthodoxy and love.
