Evangelism in a postmodern world

Tim Keller recently spoke at the Desiring God national conference, titled The Supremacy of Christ in a Postmodern World. His talk was titled "The Supremacy of Christ and the Gospel in a Postmodern World." He draws on the insight of two of my heroes, Martyn Lloyd-Jones and Lesslie Newbigin and offers penetrating insight into the modern historical situation, historical methods of communicating the gospel, and how we must repent in order to be used.
