Every now and then I see a car with a bumper sticker on it that reads:
Warning: In case of rapture, this car will be unmanned.
It always sounded a bit scary to me (I'm not very interested in the end times, I've got enough to concentrate on in the here and now), but I generally regard it as a profession of faith and don't dwell on it all that much.
A few years ago, while I was visiting my brother at his fairly liberal seminary, I heard some seminarians talking about either a bumper sticker they had either seen or think should exist:
Warning: In case of rapture, I want your car.
I chuckle to this day...
