On February 4 of this year, the Christian world commemorated the 70th anniversary of the birth of Dietrich Bonhoeffer, the Lutheran minister-theologian hanged by the Gestapo in the waning days of World War II. Bonhoeffer was only thirty-nine years old at his death; his influence on the Church in Germany seemingly at an end. And, yet, today a generation and a half later, Christians are still inspired and challenged to a more genuine faith by his letters from prison, and by his The Cost of Discipleship, Life Together, and other writings. In many ways Bonhoeffer has been more influential after his martyrdom than he ever was during his teaching and preaching career in the years prior to his participation in the conspiracy against Hitler.
