Dietrich Bonhoeffer - theologian, pastor, martyr - is one of the most significant Christian witnesses of the twentieth century. His writings challenge us to address the presence of God in the world and history. His courageous resistance against Hitler, his imprisonment and execution dramatize "the cost of discipleship." These selections, with a poignant introduction by Robert Coles, provide a penetrating entry to the heart of Bonhoeffer's message.R. Coles, ed., Dietrich Bonhoeffer
