NT Wright recently spoke at Roanoke College. I wasn’t able to attend because I was off judging a science fair, but the audio is now available for download. You can find it here.
Be aware it’s a very large file… 90mb. Also, the second link under Wright says it is for a video file, but it’s actually an link to audio of Mark Noll’s lecture on the global south (which may also be worth checking out).
