Crossway has just published Heralds of the King: Christ-Centered Sermons in the Tradition of Edmund P. Clowney, edited by Dennis Johnson. It's a collection of 11 Christ-centered sermons from friends and students of the late Dr. Clowney (1917-2005). In addition to the sermons, each contributor talks about the impact of Clowney upon their own preaching in general and this sermon in particular.
For those who would like to listen to Dr. Clowney's own preaching, you can do so at the Edmund P. Clowney Legacy Corporation hosted by SermonAudio.com.
If you want to listen to Dr. Clowney's classes on preaching Christ (from the OT, the Psalms, the Gospels, etc.) just register for the free audio archives at WTS.
And at RTS on iTunes you can listen to a team-taught class by Clowney and Tim Keller on Christ-centered preaching.
On a plane ride yesterday I read Iain Duguid's excellent sermon on "No Condemnation" from Zechariach 3--a passage, Duiguid says, that illustrates double imputation ("my sin laid on Christ and his righteousness credited to me") as clearly as any text in all of Scripture.
I also read Tim Keller's sermon on Leah: "The Girl Nobody Wanted" (Gen. 29:15-35). I'm somewhat embarrassed to admit that I've always seen Leah in this narrative as both annoying and one to be pitied. But Keller shows the profound relevance of this story for married people and for singles--and also shows us how Jesus and the gospel is the ultimate point.
I'm tempted to summarize it, but that wouldn't do it justice. But if you have a chance, it's definitely a sermon worth reading--one that will stick with me for a long, long time.
