Christians: What kind of heaven do you believe in?

[Minimalist]

I suggest you read Revelation 20

Lucky for you then that said book was voted in to the canon - probably at the Council of Carthage in 397 since it is not part of the Codex Vaticanus.
Without it you would be at a loss.

I haven't got much use for documents which are voted on by committees. It would be like worshiping a Congressional Conference Report. Even Martin Luther thought it was a piece of shit...

In the 16th century, Martin Luther initially considered it to be "neither apostolic nor prophetic" and stated that "Christ is neither taught nor known in it,"[33] and placed it in his Antilegomena (his list of questionable documents), though he retracted this view in later life.

until it dawned on him that it would be useful for scaring the dolts.... a function which it still serves today.
