He created them to Live on it forever. Read that verse, it tells us that if they did not eat from the tree ( obeying God ) they would have continued to live. It is right there!
OK, I'll bite (but only because no one else has replied - I don't really care about this).
I think we're starting to go in circles pretty fast here if we go down this path ('everyone' here has agreed with the above (quoted) statement at some point, since we've all been JWs, and some still are. So this is nothing new)
So. Had they not eaten of the fruit of Knowledge, they'd have lived forever, as per the scripture you quoted. Yes, it's logical. However - if they were created to live forever from the start, then what was the purpose of the Tree of life? Remembering that God said to remove Adam and Eve before they could eat from it, or they would live forever, even in sin. In other words; the Tree of life would give eternal life. That's what the Tree of life does. But if they were already created to live forever from the start, then the Tree of life would have no function.
It seems therefore, that one of two things must have been true:
Either they would have been given permission from God to eat from the Tree of life and live forever after a period of time in which they had been tempted and had resisted temptation (but they were never told not to eat from that tree, so they wouldn't need a later permission, so this doesn't really work).
Or they had been eating of the fruit of the Tree of life pretty much every day, and would have to continue doing so in order to live forever. After they sinned, they were cut off from it.
But neither of those two I think is in accordance with JW teachings.
