-Removed-1) I’d go by what the Bible says. I haven’t read Revelation in a long time, but if only two are mentioned in Revelation, I would say only two exist. How would I know otherwise since I’ve never been in heaven?
2) I would say just the one that was in the Garden of Eden. Why would the tree of life need to be guarded in heaven? Isn’t God’s will always done in heaven?
“Thy kingdom come, Thy will be done in earth, as it is in heaven.”
(Matthew 6:10)
3) I think people in heaven already have eternal life. Why would they need to eat fruit to get that?
4) I think the leaves are literal. How they heal the nations, I have no idea and couldn’t venture a guess since I haven’t read Revelation in a long time.
-Removed-What contortions?
The tree of life in Genesis was subject to the curse God put on the earth and likely perished in the Great Flood as nothing that is cursed would be in heaven.
Revelation says the tree of life is on either side of a river, meaning there are at least two.
It’s intellectually lazy to just claim something is symbolism without explaining what the symbolism represents or means.
