You can trace my morals to the 10 commandments where killing, lying, stealing and cheating are forbidden.
Except when god commands it in the rest of his holy book. Yeah, makes pefect sense. Or are you now trying to pull "the law changed with Jesus" which will chuck out the 10 commandments as well as your ludicrous origin story.
Interesting is only that you actually seem to think to get away with claiming that the bible does not say what it says. You've been told before: this "taken out of context" bullshit you christians desperately try to get away from all the ugly parts in the bible just won't fly.
The real question is, were those people truly Christian doing God's will?
No, the real question is how far you are willing to twist yourself into a pretzel to deny that your oh so moral god specifially endorses slavery (and rape, genocide and...) and that people following this somehow weren't true christians.
The part you still don't understand is the reason you even know there is right and wrong is because God has revealed it to us
By kicking the two people out of the garden who learned about it? Nice and friendly god you have there. Also, how would they have known it was wrong to eat from the tree if by definition only the fruit would make them aware that what they did was wrong?
