I just returned from teaching at Mars Hill. It was incredible. What amazed me the most was the capacity of that many people (maybe 8,000 all told) to engage a 45 minute teaching on "The Spirituality of the Cellphone." Mind you, this included material not often found in the pulpit--you know, extensive McLuhan theory, cultural analysis, etc. Who are these people? It says a lot about them and what Rob Bell has helped create. Truly amazing. I was honored and blessed.
I also did a two hour teaching for the Mars Hill staff on "The Electronic Gospel: Why Changing the Methods Always Changes the Message." They were a delight, very bright people. Of course, by the end of it all I was spent. I don't understand how Rob (or anyone else for that matter) does three services at that scale every week. It renewed my appreciation for the simplicity of a single service. Looking forward to the more modest 20 minute sermons I get to do back home.
