Earl, you may find some help in pondering these words that T.E. Wilder posted on the board a long time ago, in a thread that was quite unrelated to your question.
Some people have taken God's remark about the man having "become as one of us" to be ironical.
Because God created man in the world, for man to be true to his nature and thrive in the world, he needs to obey God's law. Breaking the law brings him into friction with both himself and the outer world.
(...)
But this nature of the world and of man, that is aligned with moral norms is not what makes those no norms normative. It is God's command that does so.
This is the point of the command in the garden, not to eat of the fruit of the tree. Adam saw that the fruit was good: that, by natural law so to speak, there was nothing wrong about eating it.
But the tree was the tree of the knowlege of good and evil. What was this knowlege? That good and evil are determined by the word of God and not by external nature (the goodness and beauty of the fruit) or by man's internal nature (hunger, desire for nutrition, etc.). The tree, taken together with God's command, gave this knowledge without man's having to eat from it. Eating the fruit from the tree is not aquiring knowlege of good and evil but going against that knowlege.
