Mark Driscoll's Preaching Non-Notes
Mark Driscoll doesn't use much in the way of notes. This seems to have aroused a lot of shock, because you know, no sermon notes. And yet, I'm not sure this is as unusual as people make out. Driscoll's argument is that you go in and study the text loads and then it'll preach itself. But also that you shouldn't copy his style. I'm not sure the latter holds up to too much logic, but the first part is surely the only way to prepare a sermon.
