End-times Trivial Pursuit

Spent plenty of time hearing about Ragnorok, or something similar, the past couple weeks.

Here was the question I posited in the interwebs and so far the answers just seem to pick apart the question. Perhaps there are two many theoreticals (or too many people convinced they can't be wrong) but I thought it was fun and end-timey, topical in a truly American drive-thru religion type of way. If you die and find that you retain some consciousness - let's say like a spirit. But that your way to eternal life and salvation is denied (due to your religion). If you had the ability to somehow tell your loved ones to convert - would you do so?

The closest I got to an answer I liked was that there are three possible solutions (1) there is no afterlife, (2) there is an afterlife but no ability to communicate about it or (3) there is an afterlife and an ability to communicate about it and all of our ancestors are assholes. That responder said she favored doors No. 1 or 2.
