The YBA Biblical Worldveiw Team recommends the following sources for speakers addressing the Postmodern worldview:
Perry Noble: Perry is the pastor of NewSpring Church in Anderson, SC. He tends to have excellent stories, narrative, and illustrations in his sermons and is one of my favorite pastors. His sermons are available on iTunes under NewSpring Church Audio and his blog is http://www.perrynoble.com/.
Steven Furtick: Steven is the pastor of Elevation Church in Charolette, NC. His sermons are available on iTunes under Elevation Church :: Charolette, NC and his blog is http://www.stevenfurtick.com/.
Matt Chandler: Matt is the pastor of the Village Church in Highland Village, TX. Matt is probably alot more reformed in his theology than most of the pastors in our association, but his preaching is solidly biblical. He is also engaging and often has great illustrations. His sermons are available on iTunes under The Village Church - Sermon Audio and his blog is http://dwelldeep.net/.
Craig Groeschel: Craig is the pastor of LifeChurch, which has several locations including a virutal campus. His sermons are available on iTunes under LifeChurch.tv: Message Series and his blog is http://swerve.lifechurch.tv/.
Andy Stanley: Andy is the pastor of North Point Ministries in Atlanta, GA. His preaching has a business/professional tone to it and he uses lots of good illustrations. His sermons are available on iTunes under North Point Ministries: Andy Stanley. If he has a blog, I haven't read it.
Granger Community Church: Granger rotates their preachers on a fairly consistant basis. Mark Beeson is their senior pastor. I don't listen to their sermons as much but their main target is males in their 30's, which tends to be the most unreached demographic segment. Their sermons are available on iTunes under Official Podcast of Granger Community Church.
