It all tends to fall apart when the "so how is X going to work in the new system" questions are asked.
It forces a believer to come up with an explanation that allows the end result promised in the literature. In this case, the Bible says we won't die and pain will be no more. So how's it gonna work if I trip and fall down an elevator shaft? Well... maybe you'll fly!
Another fun one - who makes the elevators? Who makes the steel for the elevators? Who mines the ore for the steel?
