I found this Fresh Air interview with Bart Erhman very interesting. For my Christian friends, he provides an exploration into biblical scholarship as well as his own journey of faith. For my agnostic/atheist friends, he expresses nicely my own beliefs on behaving ethically and fully. And for my friends who are neither, I think you’ll just find it interesting.
At the above link, you can not only read a summary of the interview, but also listen to it. I highly recommend listening.
