Ravi Zacharias' new book,
The Lamb and the Fuhrer, looks good. Here's a description:
Hilter’s name is synonymous with power, evil, and genocide. Jesus’ name with love, peace, and humility. Put the two in a room together, where they are visited by Dietrich Bonhoeffer, executed by the Nazis for his association in a plot to assassinate Hitler, and you won’t believe your ears. This third book in the intriguing Great Conversations series takes Jesus to the twentieth century to confront one of the world’s most influential people of all time––and address fundamental issues of life and death, violence and the value of human life.
