Thank you! I remember there were two or three other Bobs on the same show, Bob Christopher was one of them.
Bob Christopher, Bob Davis, and Richard Peifer were on staff with People to People Ministries with Bob George. They have changed the ministry name after Bob George's departure - it's now BasicGospel.net. You'll find very similar teaching there with a radio archive also available.
If you enjoy all those guys, you'll REALLY enjoy Andrew Farley . His website is AndrewFarleyLive.com. He has a really, really good series page as well as his weekly message archives.
Grace and peace to you!
