That's a great question. Wouldn't it be awesome to see them in their short sleeve shirts and name tags ringing Allah's doorbell? A billion and a half new mormons! Plus those Middle East oil theocracies now channeling their revenue to SLC? Niiiice.
I mean, hell, why don't JC and The Big Guy drop in on the Pope? Boom! Another billion mormons right there, plus a lot of pricey real estate; Jesus & God are big into real estate, no?
