They managed to brainwash you into hating the human world but have ironically failed to make you reject all human technology. Could it be because their business requires the press and other propaganda methods to reach you? Do they also want you to fight a war with weapons better than sticks, stones or gardening tools?
Most of Christianity doesn't believe in an earthly paradise and there are many reasons for this, outside of the interpretation of human tradition like the Bible. If you're still bound to a material world, it's unrealistic to still be living as well as to live eternally and to not suffer.
Then again, a spiritual world can seem very boring especially from scripture, with angels dedicated to sing praises forever. And there's no point to try to relate any of our current pleasures to it, there's no flesh, so sex, no hormones... A brain in a vat fed drugs and lost in its delusions would still be human, but heaven is beyond human. The appeal of such a heaven is limited for many.
In an Earthly world, especially if everything was destroyed, without the slow progress of technology and science, you might be a farmer paid with beer and grain. And needing to kill and burn animals for their burning fat odor to calm down Yahweh-Baal's anger so he doesn't torture you too much or decide to smoke your own fat. But you could also finally play with wolves and lions turned into sheep. If he bugs you too much, you might want to pray to Enki, but the jealous demon will hate you even more for it. He might also order you to go push women he hates down windows for them to get eaten by dogs.
Or, you might realize that there's no heaven or hell, just the underworld.
Even better, if you're aware of all those traditions and understand them as such, make up your own afterlife fantasy: you can move up and down as you like in dimensions of various "material" qualities, and... but are there to be other beings there? If so, will they profit from you as you will from them? Will they all just be flying around and making love? Will they then also kill eachother mercilessly in another subdimension just for fun, while immortal, like in video games?
This is of course, all sarcastic.
Edit/Adding:
I thought I'd just end this more fairly: the reality of death is difficult to handle, hence all those fantasies and traditions. Love those you love as you can when they're still alive. Live your life when you're alive, don't get tricked into surrendering it to exploitators who tell you that the real life for you is after your actual life. Don't let them make your life miserable.
