In my view to know good and evil (as told by satan Gen.3v5) is not nearly sufficient to be like God,there is much more to it as GOD tells us in Gen.3v22. It would take the addition of the tree of Life (HS) to make man like God.
Let me ask you a few questions: If I had deceived someone, you suppose I would be held accountable?
You think that the Serpent should be held accountable?
If the answer to both is yes, then the deceived are held guiltless right?
With that in mind read the following verse: Rom 8:20 For
the creature was made subject to vanity,
not willingly,
but by reason of him who hath subjected the same in hope,
That verse opens up the understanding that Adam and Eve had no choice in the matter, and that the tree of knowledge is simply the ability given Adam and Eve to make choices between two extremes.
God purposely set that tree in the Garden, or in other words, the tree was given in a creative design, making of Adam and Eve like as gods, lower case g, but not sons of God.
God could not create a vessel with free will without giving the vessel the ability to reason.
An animal can not reason or make a choice between what is good or evil, so an animal cannot be like as gods, as we are, therefore is not subject to the vanity that mankind is.
But as the next verse indicates, it is the responsible one who makes reparation for the creative design fault.
Rom 8:21 Because
the creature itself also
shall be delivered from the bondage of corruption into the glorious liberty of the children of God.
Who does the delivering here? Is it not God, the one responsible?
If that were not so, why then would Jesus have to suffer? Do you suppose that God had to subject His Son to the same vanity in order for Him to redeem our lost souls?
Read: Act 3:18 But those things, which God before had shewed by the mouth of all his prophets,
that Christ should suffer, he hath so fulfilled.
The tree is a symbol both of knowledge of good and evil and.... of life.
Therefore, if the tree of good and evil caused our demise, then by the same token, the tree of life is our blessing.
But the tree of knowledge is a curse as the law defines our lost state.
It is stated: Gal 3:13
Christ hath redeemed us from the curse of the law,
being made a curse for us: for it is written,
Cursed is every one that hangeth on a tree:
Is not the law a curse? Who of us could fulfill the whole law? Therefore cursed we are.
The Serpent is cursed making him accountable, and was hung on the tree.
You recall reading: Num 21:8 And the LORD said unto Moses,
Make thee a fiery serpent, and
set it upon a poleLike a tree maybe?) and it shall come to pass, that
every one that is bitten, when he looketh upon it,
shall live.
Let me add another verse: Exo 7:9 When Pharaoh shall speak unto you, saying, Shew a miracle for you: then thou shalt say unto Aaron,
Take thy rod, and cast it before Pharaoh, and
it shall become a serpent.
Is it not interesting that the rod became a serpent, seeing that it is a miracle of God?
And did the (Rod of Moses)Serpent of God not consume (Swallowed up) the other two serpents rods?
Well, the word consume is a positive word in that God is an all consuming fire!
Adding still another verse: Isa 5:26 And
he will lift up an ensign (A standard)to the nations from far,
and will hiss (what kind of noise does a serpent make?)unto them from the end of the earth: and, behold,
they shall come with speed swiftly:
What is the standard seen around the world? Cross?
Zec 10:8
I will hiss for them, and
gather them; for
I have redeemed them: and
they shall increase as they have increased.
But many will: Lam 2:15 All that pass by clap their hands at thee;
they hiss and wag their head at the daughter of Jerusalem, saying,
Is this the city that men call The perfection of beauty,
The joy of the whole earth?
Is that not the same as ridiculing Jesus on the tree?:
Mat 27:40 And saying, Thou that destroyest the temple, and buildest it in three days, save thyself. If thou be the Son of God, come down from the cross.
Mat 27:42 He saved others; himself he cannot save. If he be the King of Israel, let him now come down from the cross, and we will believe him.
Mar 15:30 Save thyself, and come down from the cross.
Mar 15:32 Let Christ the King of Israel descend now from the cross, that we may see and believe. And they that were crucified with him reviled him.
After all that, now we have access to the tree of Life via the Son of the living God to become sons of God by birth.
There....you see....that is the beginning of life, not the former, for the former brought death.
Hope I didn't over explain it.
Note: the rest of your post is correct by my view.
