Hey, I hope you'll think about reading the recent biography by Eric Metaxas called Dietrich Bonhoeffer: Pastor, Martyr, Prophet, Spy.
The biography reads more like a novel at times. Yeah, it's a thorough and scholarly work, but Metaxas (also the author of Amazing Grace about William Wilberforce) tells the story of Dietrich's life in a personal and passionate way. Dietrich has blazed a trail for those of us today who see dark cultural storm clouds looming and growing black overhead. Dietrich's life not only teaches but shows us that God is real, that we who are His children have no need for any fear, even should we be imprisoned or killed, and that instead we should shine like stars in the night, diligent to help the Church and do each day's simple task with a spirit of gratitude, though faced with terrorists above and below.
