Here is a link to a sermon proclaimed last year by one of my former Seminary professors, Dr. Jeff Gibbs. (The link was brought to my attention on a sermon e-mail discussion list.)
Anyhow, here is the information:

You will need to click on sermons. Currently it is the only sermon, and as you can see he preached this on Epiphany 2007.
And I will probably borrow some of his ideas.
