A while back I reviewed the book The Divine Conspiracy by Dallas Willard. This book launched a revolution for me in terms of how I think about my faith - and even though it came out almost 20 years ago - I'm still reaping rewards from his insights.
They say you get what you pay for - except some times you really don't - for instance - what we "pay" for Grace is nothing compared to what we gain. And - here's a great deal for all you deal-lovers out there: there is a series of lectures by Dallas Willard on The Divine Conspiracy - so if you're not a reader and you'd love to enjoy a brain-engaging theology class - here's the whole 12 part lecture series - for free. I've watched them all and taken copious notes - and spent quite a few of my daily dog-walks pondering all the ponderables. What I've always appreciated about Dallas Willard is that he was not only a professor of theology - but a professor of philosophy and he was a minister - he uniquely merged these instead of teaching as if only one of those disciplines existed.
While there is nothing specifically in any of the titles of these lectures about speech - they all deal pretty directly with Christian character and conduct - and how to actually experience the authentic transformation we long for in our character and conduct. That said there is plenty Dallas has to say about the way we speak along the way. These lectures have been wonderfully helpful.
There is easily 15 hours of video to watch here - and I'm already watching them for the second time. They are worth the time. A big thanks to Dan Carlson for passing this series along - I had no idea it was out there. I'm so grateful that these are available. All of the links below will open up in YouTube.
