Why would God deny man immortality

Genesis 3:22
And the LORD God said, "The man has now become like one of us, knowing good and evil. He must not be allowed to reach out his hand and take also from the tree of life and eat, and live forever."If the man had absorbed the knowledge of good and evil and was like a God then the man would have been good as God is.Why would God deny a good man immortality. As a good man, he would get to Heaven anyway.If man was not to become as a God, why did God give us the tool of the tree of good and evil.
This tree, the Bible leads us all to being good. We are in fact asked by the Bible to become as Jesus. Perfect.Why deny “the man” immortality at that point in time?Regards

While it is a fascinating question, I'm not inclined to promote this topic as written because the OP is primarily speculation outside of what is written in the Bible or other sources and doesn't provide any support for a position from real sources.If you wish to rework the OP, let me know, otherwise if another admin does not take up your cause by Saturday, I will close this PNT.Edited by AdminPD, : Typo
