This is a great sermon by N.T. Wright just given on 10/10/10 at Duke. He speaks on "Walking Alnog the Border" referring to our precarious position between the Kingdom of God and the Kingdom of this world. And, if you don't know about it, there is a great website for keeping up with all things N.T. Wright on the web at ntwrightpage.com!
Also, if you are a connoisseur of continental philosophy, or just like John Caputo (What Would Jesus Deconstruct), Tripp Fuller of Home Brewed Christianity has made available some audio files of a class Caputo is teaching on deconstruction and Derrida.
