In recent days my church, Crossway Community Church of Bristol, WI has posted a number of talks that I think will be of help to Christians and non-Christians who want to understand certain theological matters better. Here are a couple listings of some of these resources.
Owen Strachan on Truth for Everyone (click on “How Can There Be Truth That Is True for Everyone?”)
In addition, you might want to check out some sermons that a group of TEDS PhD students, including myself, recently preached at Grace Church of Walworth, WI. Scroll down a ways and you’ll see my name a couple of places. If you’re interested in hearing my preaching, that should give you a taste. I would also highly recommend the sermons of Andy Naselli, Jared Compton, and Mark Rogers, my fellow PhD students and fine young preachers all.
