I think Christianity is true, even if Islam where to rule the world

Wouldn't that be Judaism, or Hinduism, rather than Christianity?

Nah fuck it, there was a time before religions evolved . . . the OG is atheism!

Jews dont believe in hellfire for non loyalists so its less relevant and doesnt sell well. Zoroastrianism would technically be more argued for the inventor of heaven and hell. But same problem. It never said "If you dont believe in Jesus then boom hell". it was more if you were a wicked person you would end up in hell, and if you were a good person then heaven.
Christianity started the "loyalty trend"

Pretty sure relevance and selling well are not criteria for being true. In 400 years if a religion is more relevant and sells better than Christianity, does it then become the relgion that is true, or would it stay Christianity, in your view?
