Here is the punch-line to this story:
Genesis 3:22 Then the LORD God said, “Behold, the man has become like one of us, knowing good and evil; and now, lest he put forth his hand and take also of the tree of life, and eat, and live for ever” — 23 therefore the LORD God sent him forth from the garden of Eden, to till the ground from which he was taken.
