Well not necessarily. If you follow the logic the time spend on earth is the assessment time, so the place you spend all of eternity is still undetermined. If your live ends to soon, you’re robbed of time to proof yourself. But this brings up another quirk in the whole logic. Why should less than a hundred years be enough to determine how you’ll spend the rest of eternity? Like, if you have been good enough in the first ridiculously tiny fraction of your existence you’re allowed to spend it in eternal bliss, if not, you’re cleansed or you spend the rest of your eternal existence in torment.
Doesn’t God have a plan. If he wants you dead then a bullet proof car isn’t going to stop that, so why have it at all? And if you died outside of the car then wasn’t that his plan? If you only get a tiny fraction then that was gods plan right?
