You've probably already seen this great video. I just saw it on Ragumuffinsoul. He says the following:
"I believe this video annihilates the idea that people want to show up to an event (church) and stand in rows and be sung and talked to.
Safety is overrated.
People want to be a part of something big.
What can we, the church, learn from The Black Eyed Peas?"
I also find the video thought provoking. It's a great video. So there you go.
