Rick Warren had a lot of great stuff in session 2. You can get a pretty good outline of it on Kem Meyer’s blog, here.
What I think I loved the most was his quote he attributed to Einstein: “You can be the smartest person in the world, but if you can’t communicate in a simple way, it’s not worth much.”
I have always taken this approach to me teaching/preaching. You can “wow” someone with your knowledge of original languages (and having that is good, don’t get me wrong), but at the end of the day, if the cookies aren’t on the bottom shelf where they can be taken and eaten, what good are the cookies?
I’m sure I will get a comment about the value of stretching people… making them reach for and work for the cookies. I agree that people need to be challenged. But the reality is that, if in our communication of the greatest truth ever know, if people don’t get it, “it’s not worth much,” (at least in the practical application of that truth).
