First, she apparently believed (she was “beguiled” by; Gen 3:13) the serpent, who had told her that she would not die, not making her believe it was not God’s rule, but that God would not enforce the rule. Second, she merely considered that the fruit was food, after all. Third—and this is perhaps the most subtly telling—she found the tree was “pleasant to the eyes.” She was beguiled again, not by the serpent but by her own thought that nothing so pleasant could have evil consequences. Finally, and most significantly of course, she considered what the serpent said: the tree would “make one wise,” a thing much simpler than what the serpent says: “your eyes shall be opened, and ye shall be as gods, knowing good and evil.” In short, she was innocent of the ways of evil and thus easily fooled; she had never experienced deceptive appearances and so reasoned badly that harmless appearance meant actual harmlessness; and she was ambitious or prideful, which was perhaps the very worst part of the sin.
