NT Wright’s Evil and the Justice of God is one of the most interesting and thought-provoking Christian books I’ve read in a while. Unfortunately, I had to return it to the library after I finished and I enjoyed it too much to take detailed notes while reading. Paul Copan has some good thoughts that reflect what I think. But I would consider it a top-notch work in surveying what exactly biblical theology has to say about evil in the world. Check it out.
