Dietrich Bonhoeffer, Lutheran pastor, theologian, opponent of Hitler, and martyr, stands as one of the boldest examples of twentieth century Christian witness. By the time that the Gestapo hanged him in Flossenberg Concentration Camp for involvement in a plot to assassinate Hitler, Bonhoeffer had marked out not only a firm Christian defence of the rights of God's Ancient People the Jews, but had sketched out an undogmatic Christianity for 'a world come of age.' The essence of this Christian vision was the belief that God is always present in Christ and always present in suffering. In a twenty-first century when trivial quarrels can still divide Christians, Bonhoeffer's witness to this core gospel truth, and his willingness to die for it, offer an enduring example. This book offers a fifteen day course in Bonhoeffer's spirituality, drawing abundantly from his writings.
