This is the last book that Bonhoeffer wrote before he was arrested by the Nazis. Pages of it were on his desk the day he was taken away and it remained unfinished. It is bold, provocative and profound. Based on careful reconstruction of the manuscripts, freshly and expertly translated and annotated, this crown jewel of Bonhoeffer's body of work is the culmination of his theological and personal odyssey. This edition is published with a foreword by Sam Wells.
