Beginning at noon today on the West Coast, The Gospel Coalition's 2009 National Conference in Chicago will be viewable live online. Pastor Mark will be speaking this evening at 6 PM (PDT), and the conference continues through Thursday. If you miss the webcast, all sessions will be available for free download this week. Mars Hill Church partners with The Gospel Coalition, a collection of pastors and ministries from various denominations and traditions, united to uphold "the gospel of Christ crucified and resurrected...at the center of all we cherish, preach, and teach." In addition to Pastor Mark, recent Mars Hill guests John Piper, D.A. Carson, and Tim Keller will speak at this week's conference. Other speakers hail from around the country, and even as far as Sri Lanka. Check out The Resurgence blog and Christianity.com for more details.
