I have a wonderful professor for Old Testamena Survey. Dr. Charles Odium, a South Africian and former Southern Baptist seminary professor. He made a very intresting statement the other night in class.
The statement was in regard to the story in Genesis where God bans Adam and Eve from the Garden then protects or conceils the Tree of Life from them.
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." 23 So the LORD God banished him from the Garden of Eden to work the ground from which he had been taken. 24 After he drove the man out, he placed on the east side [e] of the Garden of Eden cherubim and a flaming sword flashing back and forth to guard the way to the tree of life.
Genesis 3: 22-24
God exhibited love for Adam and Eve by taking away their ability to eat from the Tree of Life and, therefore, live forever. Denying access to life eternal was a gift of Grace from God.
Had God allowed Adam and Eve to eat from the Tree of Life and live forever, they would have spent eternity living in sin. That IS HIS Grace.
