The 40-Day Journey with Dietrich Bonhoeffer introduces Dietrich Bonhoeffer, a well- known and courageous German theologian and Lutheran pastor, who during the Nazi period was imprisoned and killed and whose writings have inspired and influenced Christians around the world.

The 40-Day Journey series invites readers to take a personal spiritual journey with a Christian leader from the past or present. Each book begins with a short introduction to the life of the leader and then offers forty chapters, each of which includes a reading from the subject's writings, scripture selections from the Bible, a journal-writing exercise, and a prayer. Each book is a rich resource for personal meditation or small group discussion anytime, but is especially valuable during Advent or Lent.
