Why what?
Think about it for a moment. For believers ... If it is the way it is... then that's how it is - By God's command as we read it, even if we ourselves as theists don't understand everything - you're either with God or you ain't.. it's that simple!
But that's a cop-out, Learner. How do you know it is what it it? Why do you acceot it?
In learning chemistry, someone describes what will happen and demonstrates it, so we know what it is. Everyone who performs the experiment agrees what it is.
In sharing an observation, a joke, or an anecdote, they make it make sense, so we can understand it. We cannot accept it as correct if it makes no sense.
Your god is described as exhibiting behaviors that, in a human, would be alarming at the least. You cannot explain how this extortionate approach dovetails with words like justice or loving. You just shrug it off as something someone, somewhere, might explain some day., a problem only for non-believers.
But if Giuliani was defending a child-trafficking pirate that way, insisting "but he just IS a great humanitarian" you would not give him the benefit of the doubt.
So, why accept that this just IS? Why admit to other grownups that you accept SUCH a poor excuse for a defense?
