Also, notice what is written about Adam and Eve and their status after they took of the tree of knowledge of good and evil: "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." So the LORD God said that the man became like one of them (the gods) knowing good and evil. (Genesis chapter 3:22)
I find Adam and Eve already knew about 'evil ' according to Genesis 2:17 because the 'evil ' would be: Death.
Also ,by Adam breaking God's law, thus Adam took the Law out of God's hands and placed the law into man's hands.
Thus, Adam set up 'People Rule ' as being superior to 'God Rule'. Which rule would prove to be the 'evil ' rule.
Mankind's long history has proven that 'People Rule' can Not establish Peace on Earth, etc.
Man's evil has dominated man to man's hurt or injury.
However, through Jesus righteous mankind will see the return of the Genesis ' tree of life ' as per Revelation 22:2.
This is why we are all invited to pray the invitation of Revelation 22:20 for Jesus to come !
Come and bring the benefits of ' healing ' for earth's nations.
