@Truean:
You seem to have us confused with Mormons (Who aren't Christians. I mean really.) Our salvation doesn't depend on our works in life, be it teaching people about Christ or giving extra apples in apple pie. Also, i'd like to think that we're a little more subtle than that, but when my Church's youth program thinks that Israel is a third world country, I have to doubt our aptitude a small bit.
They just haven't fully explained the missionary rewards program to you yet. See, if you go all missionary and convert a country or something, then you might get beautified as a saint or whatever. They'll use your bones as relics and you might even get a day on the calendar, which they screwed over Galileo and would've screwed over Copernicus if they could've for making more accurate for them!
Or, maybe you'll at least get to be the patron saint of something.
Of course, just like everything else, the real benefits are in the mechan'izing! Its all about the medals, shrines, stained-glass windows, murals, shrines, but especially the medals. Check out those St. Christopher and St. Jude medals, man. They gots people payin' to be all wearin' 'em 'round their necks! I'm sure they have a saints club or something up there, or that they at least get to cut in line at the afterlife salad bar or something. Plus, you know everybody's waitin' for those saints to come marching in!
I can't even get tickets for that and I'm trying to buy them waaaay in advance.
Then again, does it really matter? You've got to be dead to get any of that, assuming you really get it.
