So when is (loving, merciful) God going to have his rapture celebration?

I wouldn't hold my breath. People, having ten fingers, and a number system based on 10, generally feel that the more zeros, the more likely. Thus, the whole thing with the new millennia. Probably they will get all fired up every 100 years, because of the two zeros. What if God thinks in binary, or hex. After all, we non-believers are told "we can't grasp God's infinite wisdom", so we certainly can't grasp his number sense.
