Does the bible say if we will ever be allowed back into the garden of Eden?
The Bible doesn't say that we will be allowed back into the Garden of Eden. It talks of a promised land Heaven that's described to be better than the Garden of Eden.
Nope, I don't think so.
The garden was probably destroyed in the flood. Sorry
Some say Eden is Paradise/Heaven. Revelation speaks of the trees of Eden being in Zion. I don't think Eden literally exists, but everything it represents will be represented in Zion.
Mormons think the garden of Eden is in Missouri so take a trip and find out.
IT IS WRITTEN:Revelation 21:1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away: and there was no more sea.
