My argument is against all who claim Adam’s nature changed after he sinned.
I just posted some comments from commentators who would agree that both Adam and Eve lusted or desired the fruit.
They show that their sin relates to how we sin. The lust of the eye, the lust of the flesh, and the pride of life.
It was true for them and is true for us. So how is it these teachers say “No, their nature was not like ours”?
To desire something is not sinful in and of itself. The fruit of the forbidden fruit was desirable. It was good for food and pleasing to the eye. There was nothing about it that made it undesirable to look at. Where Eve got into trouble was believing the lie of the serpent. "You will not die but will become wise like God." Even that sounds desirable.
4 But the serpent said to the woman, “You will not surely die. 5 For God knows that when you eat of it your eyes will be opened, and you will be like God, knowing good and evil.” 6 So when the woman saw that the tree was good for food, and that it was a delight to the eyes, and that the tree was to be desired to make one wise,[
b] she took of its fruit and ate, and she also gave some to her husband who was with her, and he ate. 7 Then the eyes of both were opened, and they knew that they were naked. And they sewed fig leaves together and made themselves loincloths.
It is questionable since she did not know good and evil that she had no clue what evil was. She only knew the command, and if she didn't know evil how was she to know that the serpent was lying to her. There is speculation in all that of course, though it is speculation that is logical from a human viewpoint. When the serpent told her that God knew her eyes would be opened and she would know good and evil can we say for certainty that she did not even know evil was a bad thing?
It was gaining this knowledge of evil that changed a human form being a creature without sin abiding in them, to one who is a being who does have sin (evil) abiding in him. He still had the same flesh, but now that flesh has something it did not have before.
I know you will have a comeback denying what was said. I have said it to you before, others have also done so. You have already agreed with the OP in principle, so there is no need to go further into this off topic conversation.
Please understand and respect that.
Thanks.
