I used to be among those who parked in this church's parking lot when it was mostly empty. I referred to ourselves as the "cast and crew" of the Sunday services. It was a responsibility, and I embraced it for the sake of service to God, but I remember I didn't like the feeling that it was a performance that required a cast and crew.
Anyhow, this morning I was impressed that these musicians and two guys on the sound board were ready for mic tests promptly 90 minutes before the 10am service time. And thankful for them. Grateful. I do feel that such a sacrifice of time is "pleasing and acceptable" to the Lord.
Nowadays I don't go to Sunday morning services. I meet with my church on weeknights or for brunch on a weekend. The cast-and-crew aspect of such meetings is little more than making sure the house is clean and food is planned for. (And I organize children's ministries, so that, too, is time that I offer to the Lord in the service of the church. And sometimes I blog.)
I enjoy the overall reduction in work, but I'm clear about this: I didn't go to home-church structure to spend LESS overall energy on the Kingdom. If I don't meet at the church twice a week anymore, but that means that I do more emailing and meeting for coffee. I don't sit in Sunday morning sermons anymore, but that means that I pursue Godly teaching in other means (podcasts, books, youtube vids, etc). Home church is more flexible, but it's not less.
