We can assume from this that both good and evil existed in the world – the serpent for one – Wrong doing existed in the world – the serpent deceived Adam and Eve.
So…we were created without the ability to discern between good and evil…G_d was okay with this – in fact He created it this way! So if good and evil existed – wrong-doing existed, if we weren’t created perfect…How did eating from the tree bring sin into the world? Wasn’t it already here- at least according to the way we typically define it???
After all Adam lied about what G_d told him (Genesis 2.15-16), apparently, when telling Eve the restrictions (Genesis 3.1-3). G_d said don’t eat the fruit…Adam must have told Eve that G_d said not to touch or eat the fruit!
What does this have to do with the realization of nakedness – and that it was wrong to be naked – when to G_d it must not have been wrong since that was how He created us and found it to be very good!
