Well.... my Trumpie fanatical religious family members are relying solely on THE RAPTURE.
You know... Donald Trump as the savior anointed from heaven then sent to earth to fulfill gods will.
OK... Whatever....
Applying religion to the answer(sorry), I believe the end will come when god is no longer needed.
Like 1000 years from now when all of our needs and desires are fulfilled by technology.
Well, maybe not 1000 years, maybe more like 3000 years.
Where technology feeds, houses, and clothes all of humanity regardless of race, creed, or continent of inhabitance.
Where technology cures all illness that would plague or threaten mankind.
Where technology fulfills our every desire and enables unlimited imagination.
Technology, as with the iPhone 100,000 plus. The human transport model.
Buy the iPhone, visit the universe. Physically.
The world will end during a time when technology becomes the answer to all want and need of humanity. When a god and the concept of a god is no longer needed. When believing in any god is no longer necessary.
Hell... who will need a god when technology replaces god? And becomes god?
So.... in that time thousands of years away, it will be god that will end the world.
Ended by that god rejected.
As scripture says, god is a jealous god. Kinda like Donald Trump.

God will have the last laugh on humanity.
So, I kinda think this is how the world will end.
In a time so very long away.
Sorry family members, but I know how you rely on THE RAPTURE. And I say, what if that rapture never happens? Instead, what if ignorant people keep electing ignorant people, and things keep getting worse and worse because you keep electing ignorant people like the Donald Trump's?
Then what?
