'Today, with the ease of access and prevalence of content, we border on the edge of cultivtaing a generation of Christians addicted to what we might call "pastoral porn." While listening to gospel preaching is a good thing, it establishes unrealistic expectations for preaching that have already made it diificult for pastors who are younger or from small towns. To pick a figure at random, I suspect Tim Keller became Tim Keller the way anyone gets good at anything - through practicing for hundreds of hours in front of a patient and loving audience. Who knows whether the next generation will have a similar tolerance level, especially if down the road they're showing Tim Keller archived sermons every Sunday.'
