I would strongly and respectfully disagree here. Even God appeared to
be aware that a fallen man could live forever. God said in Genesis
3:22: "The man has now become like one of us, knowing good and evil. He
must not be allowed to reach out his hand and take also from the tree of
life and eat, and live forever."
If it was incompatible for man to be both Fallen and have eternal life,
then God, here, was worrying needlessly. If it was incompatible for man
to be both Fallen and have eternal life, then if Adam ate from the tree,
there would be no accompanying eternal life. There would have been no
need for God to have banished man from the Garden nor to have removed
access to the tree of life. But clearly God was worried about this
possibility and banished man and woman from the Garden and placed a
cherubim to guard the tree. Sounds like an awful lot of worry for
something that is impossible.
