Mustard- But it goes much deeper. "Trust" is a "reliance on the character, ability, strength, or truth of someone or something".
I would ask, are ALL of these traits needed for trust? Or how about any one of them? Adam knew of God's ability. The ability to create. To bring something forth into existence that wasn't there before. His wife for example. And his reaction/response to the sudden presence of his wife was positive, it was good. Couldn't Adam trust that God could do this again?
How can they rely on the "truth" of God when they don't even understand what "lies" are? What we would call someone's "character" is based on whether they believe and display "good" traits, and not "evil" ones - none of which Adam or Eve would be able to decern.
Yet the snake was very selective of his words and method. It wasn't just random gibberish. Why?
The snake asked Eve to repeat the very exact words of God, 'is it true that God said you WILL die?"
Eve responded with 'yes'. How do you explain that she understood how to respond correctly, and not be confused by what the snake asked?
Further, the snake resorted to a temptation... that they would be like God. It wasn't sufficient to leave it at 'you will not die'.
Why did the snake resort to it? Doesn't the inclusion of a temptation imply that Eve had sufficient intelligence and mental capacity to require a sleight of hand? Otherwise, any gibberish spoken by the snake would have been sufficient to induce the disobedient act.
