Hi!
No, what I am saying is that regardless of their foreknowledge on regards to what sin is, they committed sin–the absence of knowledge did not remove the culpability.
Their transgression was taking the creatures word rather than the Creator’s.
Say you and I are friends; I am visiting you and you warn me that the bathroom sink is broken–I’m not a plumber, but, as many, I dabble into the arts (‘I can do it!’); so after using the toilet, instead of employing the sanitizing foam dispenser, I insist that I can use the sink (to my untrained eyes, it seems perfectly ok); water floods–by the time I notice the problem and shut off the faucet the wall and floor in your bathroom are drenched.
Can my ignorance of the problem with the sink undo the drenching of the wall and floor?
Now take that to the spiritual level.
Can Adam’s and Eve’s lack of knowledge about sin undo the fact that their transgression was sin?
Maran atha!
