Reading your responses to others I've come to respect your approach to YA.
1) Genesis; Tree of the Knowledge of Good and Evil; it's an idiom, common the region despite the West being unfamiliar with it. It means to partake of, and thus to partake of the concept of Good and Evil. We are told not to judge. When Adam and Eve partake of it, they show anger, fear, shame, lie, evade, and otherwise show all the signs of thinking of the world in simplistic "good and evil" terms.
God does not. God has no such limits.
He warned us not to.
We built entire religions on our own major flaw, the one thing he didn't wish up on us.
There is nothing innately good or evil. it's a simplistic evasion of reality that leads to misunderstandings and pain the world around.
Everything God warned us about is translated by man into these terms, to mankind's detriment.
One commandment (there are hundreds, not just ten, but Paul narrowed it to ten for the would-be semi-Jews) was not to eat pork.
In an age when one couldn't be sure that the meat was cooked fully, trichinosis is a great danger, the parasite being deadly and painful.
Yet, now we know what it is, how to fight it, and it is almost nonexistent now.
Would God give the same commandment now?
Is it a sin to eat pork?
A sin is a mistake. God does not condemn mistakes, if you look at the pattern.
He sets aside those who constantly strive to correct their sins, to own up to them and fix them (not just pretend).
Heaven is the place where God lives, and his invite is to those who know how to behave in a way he finds pleasing.
Would you invite to your house those who don't behave? Or restrict it to only those who make no mistakes?
No, I'm not religious, but world religion is a study of mine.
