In this edition of Author Sketches we talk to Dallas Willard, University of Southern California professor of philosophy and author of several highly influential books about the Christian life including, The Divine Conspiracy, Renovation of the Heart, and The Great Omission. His new book, Knowing Christ Today, tackles the subject of spiritual knowledge as a valid and reliable source of belief. We talked with Dallas about the book, the current crisis of Western culture and religion, and the urgent calling of Christian pastors as "the teachers of nations."
