In Genesis it mentions the "tree of life" that Adam & Eve were never to partake of... they ate off the "tree of knowledge" and then God forbid them from everlasting life. He stationed angels and a flaming sword there to protect the tree.
What happened to that tree, the flaming sword, and the angels?
Do you think the story was literal or like other misunderstood things, symbolic? Do you think a tree that produced fruit that gave everlasting life would actually die itself? Or would a tree producing everlasting life fruit be an everlasting tree itself?
