If Jesus says, "I and the father are one", then even the "not my will but your will be done" is suspect. . . . . in my opinion, of course.
As I am drifting away from the topic, I'll agree to disagree with your opinion on Jesus' temptation. :nod
But as per the topic, I'm not sure if I have ever heard anyone state that "Eve didn't actually sin". But if we say that Adam would have had to express a desire TO disobey god "by desiring to do what Eve wanted over his god", then I think that it still must be concluded that Adam sinned in his heart before actually performing the action.
I'm still not sure how Eve "listening to Satan" would "not be a sin", though, and even her decision being made prior to "taking the bite".
Oh, the fact that Eve was deceived is quite biblical. Walk through these texts with me, and I think you will agree that the bible teaches that Eve was deceived and Adam decided to sin...
1 Timothy 2:14 "And it was not Adam who was deceived, but the woman being quite deceived, fell into transgression."
Here it is stated, flat out no "interpretation" necessary that Eve was deceived and Adam was not.
Romans 5:12 "Therefore, just as through one man sin entered into the world and death through sin, and so death spread to all men, because all sinned..."
This text clearly states that sin entered into the world through one man. Since we know that Eve ate the fruit prior to Adam, it follows that because Eve was truly deceived, she "fell into transgression" as opposed to "deciding to disobey God". Romans 5 carries on this theme throughout the rest of chapter 5 as it compares how Adam's sin resulted in the fall of all men and Christ's obedience results in the justification of life to all men. (Note: off topic but for clarity, justification of life isn't saying all men will be saved, but that Christ's death provides the justification for all to be saved.)
Another interesting passage to consider is Genesis 3 after the fall.
God asks, "Who told you that you were naked? Have you eaten from the tree of which I commanded you not to eat?"
Here is Adam's answer: "The woman
whom Thou gavest to be with me, she gave me from the tree and I ate."
God reinforced that He had commanded Adam not to eat from that tree. Eve wasn't on the scene yet, the commandment was given to Adam alone. You can check that in Gen 2:15-25. Adam, when confronted with what he had done, blames not just Eve, but God Himself, for the sin of eating the fruit.
When God asked Eve what had happened, she states, "The serpent deceived me, and I ate."
When God then hands down the consequences of the sin, note what He states to each person present:
To the serpent He says, "Because you have done this, cursed are you more than all cattle, ...and I will put enmity between you and the woman, and between your seed and her seed..."
So, the serpent, solely because of his actions is cursed and God sets enmity between not the man and the serpent, but the woman and the serpent.
To Adam, God says, "Because you have listened to the voice of your wife, and have eaten from the tree about which I commanded you, saying 'You shall not eat from it'; cursed is the ground because of you; in toil you shall eat of it all the days of your life. ... till you return to the ground, because from it you were taken; for you are dust and to dust you shall return.'"
Here we see that death does indeed come through Adam and God clearly tells us why, because Adam listened to Eve rather than to God.
Eve received no "Cursed are you" type of statement. God tells her that her pain in childbirth would be greatly multiplied and that her desire would be for her husband and he shall rule over her. That's pretty much what Eve faced.
This is why I believe that Eve was deceived rather than purposely sinned.
As for Adam, yes, I agree that his sin started before he ate. God Himself reinforces this idea when He cursed Adam saying that Adam listen to the voice of his wife rather than to what God said.
Is it a sin to listen to Satan? No, not particularly. We know this from the story of Job when God Himself listened to what Satan proposed. Even if Eve had obeyed what her husband told her rather than followed through on eating the fruit, there would had been no sin just because she listened to Satan. It's not a good idea to listen to Satan. I don't make a habit of it myself. But, it's not sin just because Satan says something to us and we listen. And, when Satan is telling us to do something that God has commanded us not to do, that would be temptation. Temptation is not sin.
