Tim Keller, Don Carson and John Piper discuss ministry and the Gospel in a 1 hour video recorded at the 2008 Gospel Coalition Leadership Meeting. A phenomenal video. Keller and Piper discuss how mercy ministries to the world can be effective outreach opportunities. Keller describes how his approach to preaching the Gospel by deconstructing legalism to a libertine culture effectively removes major barriers to the Gospel. Keller also describes a difficulty in finding pastoral staff who have strong theology, a serious moral trembling, and an experimental heart passion for the person of Christ. Piper asks Tim to explain Gospel-centeredness, and then raises a question of how a man addicted to pornography can successfully see victory over that sin via a Gospel-centeredness. Then Carson asks John to explain how God is not a megalomanic by demanding worship and seeking glory.
