As a tribute to Dr. Robert J. Ostenson (“Dr. O“), a number of sermons are provided here that he preached in the 70s and 80s while he was the senior pastor at Trinity Presbyterian Church in Montgomery, AL. I (Roger) am in the process of digitizing the cassettes my Dad collected many years ago (and has since listened to dozens of times) that contain these sermons. As I digitize and edit them for clarity I will publish them here. This is an ongoing project. As of today (15 June 2014), Dr. O’s first four sermons on the Ten Commandments have been posted. Stay tuned!
