You need to get on Facebook. You are probably already on the most popular social networking site in the history of the internet, but if you aren't you need to change that. Facebook is where people are going to communicate and connect with new and old friends. Sure, that's nice.
But Facebook is where your sermon can gain the power to really connect to people where they are. It's way too easy to prepare a sermon while sitting in an office behind a desk with no connection to people. But sermons are all about people. One way that I found to connect the two is to pose questions on Facebook as they come up in my sermon prep.
Don't try to clean it up or explain the background or exegete the text. Just ask the kind of honest, gut wrenching questions that real people ask.
If God is good then why do bad things happen?
Do I have to be perfect?
Is it ok to kill people?
Why are kosher laws not in effect any more?
Ask these kinds of questions and then stand back. The results are great and the connection with real people is amazing. I found so much fodder for my sermons using this method, that I don't think I'll ever go back.
