Fleeing the firebombing of his native Dresden at the age of 15 in February 1945, the author found an answer to the question that haunted him: Is there a gracious God, and if so, how do I respond to the challenge of that knowledge in the face of so much pain and suffering? He found his answer in the writings and witness of German theologian and martyr Dietrich Bonhoeffer, hung as a traitor by the Nazis in 1945. These lectures and sermons over a long career as a Lutheran pastor and professor provide insights into how one reconciles the gospel of Christ with the reality of Bonhoeffer's "world come of age."
