It's not the same thing. No-one's obliged to believe anything because a book or their tribe tells them to. If God never responds, why would anyone go on? Oh Lord, won't you buy me a Mercedes Benz. But God does respond, in a definite way, perhaps tailored to that soul's own perception. It may be very subtle. But it will be clear. God may even respond by talking everything away. Sometimes it may be necessary to lose everything. It is natural, after experiencing this 'touch' to still have doubt in future, but it's not the same as blind belief. Knock and it will be opened. I have to drop out of this discussion now, because I sound bombastic and know-it-all and open the door to the mockers. EDIT: It's not restricted to any religion. God responds to the searching soul, any time, any place, any religion, imo.
