We just participated in (by internet) what I thought was a remarkably powerful worship service at Northland Church out of Florida. The sermon was on Psalm 84 (How lovely is your dwelling place...) and work. If you're interested, I would definitely recommend either dropping in on the whole service or downloading the specific sermon.
You can log in and watch the whole service live tonight at 6 or Monday night at 7 at this link.
Or when it becomes available (soon I would guess) you can download the sermon by video or audio here.
