It was not God, but the serpent that said "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. " What Adam lusted after was also that of the fruit being pleasant to the eye and partaking of the fruit as not knowing the serpent was beguiling the both of them. How many times have we done the same thing.What was it of the fruit did he lusted after? Was it not the he would be as God, knowing good and evil? When God barred the way to the tree of life, did not the Lord say man has become one of us, knowing good and evil?
Gen 3:4 And the serpent said unto the woman, Ye shall not surely die:
Gen 3:5 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.
Gen 3:6 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.
