Keller & Clowney: Preaching Christ in a Post-Modern World

I love sharing God's word through preaching.  Since I'm moving to preaching every week, as we launch The Exchange Community in Jackson, Mo, I thought It would be good to reexamine my preaching and how I interpret and display God's word.  I remembered a friend of mine shared, a number of years back, that Tim Killer and Edmond Clowney team taught a class at Reformed Theological Seminary on Preaching Christ in a Post-Modern World.
