>On the other hand, I understand his religious sermons better than technical stuff. So it helps my self-esteem to read on something I have a clue. Also, what if he is right and we all go to hell? I am just trying to hedge ...

ОК, here's a hedge: you have two variables - there's life after life as they describe it, and then you pay - or not. Then, two possibilities: you behave as if it was true or you don't.

Case .t., .t. - the afterlife exists, and you are rewarded for the good deeds in your life. You win.

Case .t., .f. - the afterlife exists, but you didn't count on it, so you lived as you liked it. You had a good life, you win; their accountant doesn't like you because you were not perfect, but you don't care - you're in good company of billions of others.

Case .f., .t. - there's no afterlife, but you thought there was; your good deeds were a reward unto themselves, you win during your life, and after that you aren't worrying, because you are not.

Case .f., .f. - no afterlife, and you weren't counting on it - you lived as you liked it, it was crazy and unforgettable, you win and there's no accountant to screw you afterwards, as there's no afterwards.

So either way, you win. Pick whichever you like, your selection is irrelevant.
