Gen 2:9...The Tree of Life was also in the midst of the garden....In Gen 3:22 -24, man had come to know good and evil by eating of the forbidden tree of knowledge of good and evil. God needed to move the man out of the garden where there was the Tree of life (eternal life) else man, partaking of it, would forever remain good and evil. Removal allowed for a man to later choose to be Good (choosing Jesus) forever instead of evil forever. Once God, through His son Jesus Christ, is sincerely chosen, God's promise is inherited; Heaven (The Eternal Kingdom). In God's Kingdom, there won't be any more evil and man will be able to eat of the Tree of Life to have Good forever. Rev 2:7 "....To him who overcomes I will give to eat from the Tree of Life, which is in the midst of the Paradise of God." Rev 22:2 In the middle of its street, and on either side of the river, was the Tree of Life............
God is good!
