Why does the fact that he refuses to impose himself where he is not wanted make him/it/her petty? Couldnt this also be a result of respect instead of pettiness? Even if it is seen as pettiness, this now puts us into the realm of interpreting God's nature rather than whether God exists or not.
Your words that promtped my comments about pettiness were: " You have acquaintances and friends. Who are you more likely to help out when they call you late at night? Would God respond any differently?"
So you're correct that we're now discussing/interpreting the discussed God's nature, but the scenario in question, which you raised, was one in which the non-believer is calling out to God, asking for help. Prior to that, I did ask why God chooses to ignore the vast majority of us, and by that I meant essentially: why do some non-believers, such as yourself, have religious experiences that they are quite sure are instances of God contacting them, while the majority of us don't? That seems, for lack of a better term, unfair on God's part.
Besides, perhaps God's enigmatic nature is for his amusment and not ours.
That sounds like a parent who has two small children and acts very lovingly and caring towards one of them, while acting inconsistently towards the other, for no other reason than to amuse himself. Beyond petty.
I have been recently musing over the thought that just because we have been taught that God is pure love doesnt' mean that it's true, does it?
It certainly doesn't sound like your version of God is. You seem to have a very unique take on him/her/it, at least in contrast to the general understanding of the universally-accepted qualities of the God of Christianity. Yours sounds far more like the YHWH of old--he was all about helping the chosen ones, at the expense of their neighbors.
