"If there are gods and they are just, then they ... will welcome you based on the virtues you have lived by."
Okay, 3 questions though:
1) Who decides what is virtue and what is vice and by what standard?
2) What method do the gods (or God) use to determine if I am welcomed? Is it simply a numeric addition (good deeds outnumber bad ones)? Or perhaps it is a weighted scale ( 1 murder == 1,000,000 compliments). Are there any bad deeds that are unforgivable? Do my deeds from my entire life count or is only the last few years (or even days or moments) that count?
3) How can I know the answers to the above? Do I simply have to be the best I can? Is it reasonable to expect that if there is a God (or gods) that he (or she, or it, or they) would reveal himself? If not, would God be just? If so, how has he done so?
I posit therefore, that it is reasonable (necessary?) to investigate different, mostly conflicting, truth claims to determine which may actually be revelation of what God actually expects from us.
