Sean McDowell interviews one of Christianity’s most perceptive thinkers, on Os Guinness’s latest book, The Great Quest. Guinness says “Western civilization is in crisis, because it’s rejected and lost touch with the faith that made it.” In this book, Guinness says, he “describes a pathway for those who … think enough and care enough to think through the meaning of life and come to their own convictions.”
