I am about halfway into the new biography "Bonhoeffer, Pastor, Martyr, Prophet, Spy" by Eric Metaxas. What a wonderful book. If you have not read this book, please do so. What an amazing life. Bonhoeffer knew what it meant to be a Christian and what it still means today. He is an example of what it really means to be a Christian and what is required if one is to claim to be a Christian.
Next up: "The First Crusade" by Thomas Asbridge.
