This audio of John Piper has just been put up by The Resurgence from a conference they had back in 2004 for church planters. I was able to go and was thoroughly blessed by the Reformission group (affiliated with Acts 29 – a church planter’s network affiliated with Mars Hill Church in Seattle). This is Part 1 of (I believe three sermons that were preached at the conference). It was at this conference that much was confirmed in my appreciation for Mark Driscoll and the Mars Hill group. May you be as blessed as I was.
