Please go visit Justin Taylor's blog. He just posted the audio from the NEXT Conference 2010.
As a pastor, who sidelines as a full-time high school math teacher, the posting of this audio is a major blessing to me. I don't have the time or the funds to go to a conference like this one, but I always wish I could because I know that the speaking is going to be worth while! Here is a list of the speakers and their topics:
Joshua Harris, What Are You Built On?
Mark Dever, The Doctrine of Christ’s Work Accomplished and Applied
Kevin DeYoung, Scripture
C.J. Mahaney, Sanctification
D.A. Carson, God
Kevin DeYoung, The Church
Jeff Purswell, The End Times
