Well let's start where you are right, that the Devil's Three Lies all imply that God lied. None of it is mixed with any truth however, All the three sentences, even the First Lie which is a crooked question are all lies, there is no truth in them. See though here in your mistaking of them for being mingled with truth to be the poison of it all, it is the twisting of the Spirit of Truth, and why it is so blasphemous this action the Devil did here. The First Lie is the crooked question with the Devil asking crookedly "Yea, has not God said ye will eat of tree of the Garden?" This is a coy lie for the First Lie of all time for God never did say that, and in fact God had commanded outright they were not to eat from the tree of the knowledge of good and evil, as the woman correctly replies. See though the subtlety, now he has called her attention to the tree forbidden, cast doubt on what God has said, and set her up for the next two Lies. After she responds correctly with the truth that God said they would die, Satan tells her the Second Lie an outright lie against God saying "ye shall surely not die." So here he has just told her to opposite of what is true and also basically said God is wrong. He then backs this up with the Third Lie saying that "For God knows that in the day you eat it your eyes will be open and you will be like God." This then does several things, for one it casts God to be the liar and the enemy and puts the woman at variance with God, it also now makes the fruit that God forbid seem desirable now, and it also creates in the woman the idea that she could replace God, essentially making her into her own idol. Taken all together the Three Lies totally overrun woman's mind and she believes the Lies, and they're all Lies, and she eats, and even after eating, gives to her the man, the real target the Devil was trying to kill because he is the image of God, but the cowardly serpent couldn't attack him directly.
1 a lie is an untrue statement. For a lie to stand as a lie, it must be a declaration, a statement. A question is not a statement but a non declarative. A question can be misleading but cannot be lie. Yes, the question Satan asked was misleading but cannot be construed as a lie. What you call your number one lie is a misleading question in my opinion.
2. Let's once again analyze what you call your third lie. You know Satan is very clever. If you look at his statement, he only picked one aspect or quality of God when he told Eve "For God knows you will be like God knowing good and evil. That is, the aspect of knowing good and evil. He qualified his statement. Were their eyes opened when they ate the forbidden fruit. Yes. Did they end up knowing good and evil? Yes. Did God know before hand the fact that their eyes would be opened and they would have knowledge of good and evil? of course yes. if all these are true, where is the lie?
3. The only lie there, is your second lie. Why is it so.? He told them they would not surely die the day they eat of the forbidden tree. Did this stand true? No. because they died as God told them. Satan categorically made a statement of lie which is your second lie.
4. The lie of the devil had no effect on the fruit of the tree and could not have made it more desirable in any way. It only had effect on Eve's imagination and thought.
Satan is Satan and his nature is to deceive and he uses all tricks in his amour to achieve this. Therefore, the scripture warns us to be wary of the wiles of the devil.
