The relationship between the verbal proclamation of the gospel and the embodiment of the gospel is a hotly debated and often misunderstood issue. My father in law authored a book, just now released by Crossway, on this very topic. He and I have been talking about it for a few years. I very much agree with his analysis and conclusions and I think you will find this interview with Justin Taylor a great primer for it.

Thanks for sharing the interview; sounds as though this will have to go on my must read list.
