In 1961 Walt Disney died. The great imagineer was no more. But with the help and art of cryonics ( deep freeze by liquid nitrogen) Walt's body is still preserved in Arizona.
He can then live forever in Disneyland.
You can pursue such expensive flights of the imagination if you have the money. For the rest of us there is the proof of an empty tomb in Jerusalem and the sure promise of it's temporary Resident that whosoever believes in Him, shall not perish but have everlasting life.
By the way our mansion will be in Heaven not Disneyland.
