"Satan desired to make it appear that this knowledge of good mingled with evil would be a blessing, and that in forbidding them to take of the fruit of the tree, God was withholding great good. He urged that it was because of its wonderful properties for imparting wisdom and power that God had forbidden them to taste it, that He was thus seeking to prevent them from reaching a nobler development and finding greater happiness. He declared that he himself had eaten of the forbidden fruit, and as a result had acquired the power of speech; and that if they also would eat of it, they would attain to a more exalted sphere of existence and enter a broader field of knowledge. Ed 24.1"
"For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil."
EGW elaborates on the serpent's claims in Genesis 3:5, providing a narrative context and expanding on the idea of becoming like gods, knowing good and evil. The confidence remains high as it's a clear development of the Genesis account.
"While Satan claimed to have received great good by eating of the forbidden tree, he did not let it appear that by transgression he had become an outcast from heaven. Here was falsehood, so concealed under a covering of apparent truth that Eve, infatuated, flattered, beguiled, did not discern the deception. She coveted what God had forbidden; she distrusted His wisdom. She cast away faith, the key of knowledge. Ed 24.2"
"And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat."
EGW's description of Eve's temptation and distrust of God directly parallels the events described in Genesis 3:6. The passage expands on Eve's motivations and thought processes, making the connection clear.
