With only 144,000 Sainted Chosen (those are Jews to you and me) and a handful of gentiles judged on the goodness of their works to enter the Pearly Gates, there sure is not much of a guarantee for a spot on that line.
For a little perspective, that's 60,000 less than the amount of babies that get aborted worldwide annually.
As for the billions and billions of Christians since way back when, hope they didn't pack too much in that suitcase.
