I'm gonna go on a bit of a rant here...My grandfather was a preacher as long as I knew him and I doubt he would have ever thought highly of the mentality you are describing. My grandfather believed in God, but he also believed in doctors. He believed miracles could happen but never on demand - and that is was hubris to expect otherwise. Nor do miracles require rays of golden light and celestial trumpets - they don't always announce themselves and are often only recognized as such after the fact.

God is highly unlikely to save you from being an idiot.
