Aunty Jane when the scriptures say, "Jehovah God then said: “
Here the man has become like one of us in knowing good and bad. Now in order that he may not put his hand out and take fruit also from the tree of life and eat and live forever."
It means that Adam and Eve decided that they would decide for themselves without God what is in the best interests of human beings and what is not in the best interests of human beings.
The first human pair were not devoid of knowledge of good and bad. God had told them that it would be wrong or bad to eat of the fruit of one designated tree; so, to obey God was good. (
Gen. 2:16, 17) So the particular “knowledge” indicated by the “tree of the knowledge of good and bad” involved a self-determining of what is good and bad. On this, Professor T. J. Conant wrote: “By disregarding the divine will, and deciding and acting on his own, man chose to know for himself what is good and evil.” Yes, Adam and Eve rejected God’s determination and chose to set up their own standard of what was good and what was bad.
What about God’s statement, “The man has become like
one of us in knowing good and bad”?
In
Genesis 1:26 Jehovah said: “Let
us make man in our image.” The Scriptures point to the conclusion that God was here speaking to his only-begotten Son, who later came to earth as Jesus. This one, the Word, was God’s master worker through whom all other things were made. (
John 1:1, 3; Col. 1:15, 16; Prov. 8:22-31) The similarity of expression in
Genesis 3:22 suggests that Jehovah was again speaking to the one closest to him, his only-begotten Son.
It would indicate that the Word already had “knowledge of good and bad.” From his long and intimate experience with Jehovah, the Son certainly learned well his Father’s thinking, principles and standards. Convinced of his Son’s acquaintance with and loyalty to these, Jehovah may have granted him some latitude, also, in handling matters without direct consultation with the Father in each instance. So the Son would to this extent be able and authorized to determine what was good and bad. However, he would not be setting up a standard that conflicted with Jehovah’s.
With Adam and Eve, their coming to know good and bad involved breaking Jehovah’s command and rejecting his standards. So Adam and Eve by breaking Gods command about the forbidden tree were saying they could decide for themselves what was in the best interests of mankind and what isn't in the best interests of mankind better than God and his only begotten Son. Satan, and Adam and Eve were saying they can live without God rulership deciding without God and bring about a paradise earth that would be without sickness, hunger, homelessness, etc without God and his only begotten Son
