Here's a snippit from Tim Keller's blog post today: Lloyd-Jones on the Primacy of Preaching...
Dr. Lloyd-Jones effectively dismantles the idea that watching a video or listening to an audio of a sermon is as good as coming physically into an assembly and listening to a sermon with a body of people. It is obviously a good thing if a person who never hears or reads the Bible listens to the recording of a good gospel message and is helped by it. But the Doctor argues that people experience the sermon in a radically different way if they hear it together with a body of listeners and if they see the preacher. Watching on a screen or listening as you walk detaches you and the sermon becomes mere information, not a whole experience. There is a power and impact that the media cannot convey.
