As times continue to change, I think the average worshipper is changing from being a responsive participant in worship to being an observational participant. Check out this video. It's from a recent opening from Buckhead church. Notice how hard everybody is working to pull off such an amazing opening. Feel the energy of the song. But watch the heads. They barely even move in response to the beat. Interesting.
At our church we talk about how to get our people to participate and be responsive in worship. I'm not sure if it's really like that anymore. I think people will respond by observing and praising, but we won't see anything that will make them stand out, especially if we continue to interact with them in the same format.
If we give worshippers a chance to interact in a personal way with a spiritual truth (prayer stations, experiential activities) I think they'll respond and really be engaged. Just thinking.
