The Evangelical Alliance and Focus Radio are producing a series of resources for young christian leaders called Slipstream. The centre piece of the thing is a monthly podcast with respected Christian leaders. You can subscribe to the podcast here if you have the right software installed.
One podcast I would point you too is the fascinating interview with NT Wright which is followed by an ‘expert’ reviewing Wright’s book Surprised by Hope. I’m not entirely sure that I deserve being called an expert, but I enjoyed doing the review!
