I have the distinct pleasure of being a member of The Gospel Coalition. TGC is a fellowship of Gospel ministers who desire to reclaim the Gospel as the central and defining message of the church. Every other year TGC sponsors a conference in which some central elements of the Gospel and its impact on the preacher and the church is examined. This coming year, the conference will be held on April 21-23, 2009. The theme of the conference is Entrusted with the Gospel: Living the Vision of II Timothy. Registration is open.
Here is a brief video of Tim Keller explaining one of the key elements of TGC conferences. You can find more videos on the conference at the website.
