I know evangelical christians that like "Let My People Think," though I can't speak to it personally. You might elucidate a little on what you're looking for, as different podcasts are going to take a different theological stance on a lot of issues (the literal truth of the Bible comes to mind). posted by jedicus at 11:19 AM on June 13
I'm gonna second the request for more information. Of late, I've been interested in Orthodoxy, and I've found the stable of Ancient Faith Radio podcasts to be pretty awesome. posted by khaibit at 11:50 AM on June 13
I haven't listened to the podcast, but I've heard him speak and liked him quite a bit. Tony Campolo calls himself a red-letter Christian, which means he focuses on the stuff printed in red in some bibles - the things Jesus said, such as feed the poor, etc. So while he is not exactly an apologist, he has a different take from the stereotypical republican christian. posted by selfmedicating at 12:35 PM on June 13

It's been many years since I've tuned in to their broadcasts, but I remember that both men had consistently excellent and insightful programs. posted by chara at 2:36 PM on June 13
