Catechisms aside, I think our purpose is to use our God-given assets to the best of our abilities, and that -- assuming there is a Heaven, Hell or Hades (ref. Homer's Odysseus) -- the questions at the gate will be ... "What where your achievements?" and "What did you do with the gift (reason) I gave you?"
[T]he questions at the gate will be ... "What where your achievements?" and "What did you do with the gift (reason) I gave you?"Can one determine here on earth whether what one does with the gift(s) one is given deserves eternal reward or punishment? Or does one have to wait for the end game to find out?
Some consider to build a house, to write a book, and to pass on the genome to the next generation to be acceptable for a life's accomplishments for those who live that long. As far as questions at the gate, I can't subscribe to that medieval nonsense. But we can each review our own lives at any time and see if we think we are doing it right or not. It's simple in America: It's money that matters - R. Newman.
I have Net Worth, therefore I am. How would Messr. Descartes have phrased that?
