The Tree of Knowledge Good and Bad

In Genesis three, verse 22, God says something about that tree. This is after the humans rebel and he says, Oh, look, the human has become like one of us knowing good and bad. And now he might stretch out his hand and take from the tree of life and eat and live forever. Humans in this narrative don't have inherent within themselves ongoing immortal life. That's something humans have to receive as a gift from outside from God through the conduit of the street.
