A Levite and his concubine

[Tonus]

What i'm saying is that, according to the bible, God is the creator and is allowed to do what he wants to do with his creation.

Is that what the Bible says? That god is "allowed" to do as he pleases? Who, pray tell, is it that gives god permission to toy with his creation?

I am assuming that you are saying that as the almighty creator of all that exists, god can do as he pleases and no one can hinder him in any way. Which means that morality is subjective: if god changes his mind, then one morality may replace another. In the story of Lot, the angels react to the demands of an angry crowd by blinding them, thus sparing Lot's daughters the ignominy of being gang-raped for a night. In the story referred to in the OP, the Levite's concubine is granted no such rescue, and her tormentors are not directly dealt with. You have no grounds for finding any of these actions to be good or bad, aside from "what did god say about it?"

It's just as well that god won't show up to prove to us that he's out there. Because imagine if he suddenly changed the rules again and said that it's okay to offer up your daughter to sate an unruly crowd of rapists?
