Joey -If there was open and free access to the "tree fo life", which granted immortality, as there was to the "tree of knowledge" - how was the serpent to know god would restrict access to it so that adam and eve couldnt live forever after they ate the fruit.
Because the snake was present when God gave Adam and Eve his instructions regarding all trees, Joey.
We know this because it was the snake himself who revealed that he was listening to God when he initiated the conversation with Eve..."did God really say...?"
So you are correct, Adam and Eve could eat from the tree of life forever and ever, something the snake KNEW. Clearly, it was the mechanism thru which God would keep them alive since God immediately restricted Adam and Eve from going near it after eating from the wrong tree.
The serpent told adam and eve exactly what would occur- if they ate from the tree of knowledge - they would know good and bad. That happened and it was confirmed by god in Gen 3: 22.
As with Simon, I agree completely with you here. But you are referring here to what the snake said after the lie. And that lie was,
"you will not die".
