Dr. Robert Smith gave a series of 3 lectures at Southern Seminary this week on trinitarian preaching for the E.Y. Mullins lecture series. I was able to attend the first and third lectures on Tuesday and Thursday, and they were fantastic. Dr. Russell Moore called Dr. Smith one of the greatest living preachers, and after having heard him, I would have to agree. If you want to hear someone truly exult in the proclamation of God's glory through preaching, take some time to watch this.
Here's his first lecture from Tuesday on Theocentricity in preaching. The others should be available to watch online soon.
