just saw this post by scott rubin, the middle school guy at willow creek. i love envisioning the scene he describes. here's a portion of the post...head there for the rest.
After our pastor spoke, we closed our service with a final song. And because the focus was not so much on the past 35 years… but on what God might want to do through our church in the next 35 years… the adult band & vocalists & choir that had led us in the first part of the service were replaced by teenagers at the instruments and microphones. But cooler than that… after the first verse of the song, all of the students were invited to come to the front of the room for the rest of the worship. For the next few minutes, the stage filled with teenagers.
