Actually, you're quite wrong in saying that Adam and Eve had never eaten from the tree of life.Where in the Bible does it say that?--undercover.They had permission to eat from every tree in the Garden except for the tree of the knowledge of good and bad.
Obviously, the angels were posted at the entrance to the Garden in order to prevent Adam and Eve from CONTINUING to eat from the tree of life. Which, btw, shows that merely eating from such tree only once would not result in them having everlasting life. It's obvious that Adam and Eve were created in such a way that they would need to regularly eat from the tree of life in order to keep on living. -- Schizm.
Here's hoping you can read.
15 And Jehovah God proceeded to take the man and settle him in the garden of E´den to cultivate it and to take care of it. 16 And Jehovah God also laid this command upon the man: “From every tree of the garden you may eat to satisfaction. 17 But as for the tree of the knowledge of good and bad you must not eat from it, for in the day you eat from it you will positively die.” -- Genesis 2:15-17.
