We've all had these discussions many times before, morality (knowing basic right from wrong) everybody has (regardless if they acknowledge it or ignore it), belief in God provides an additional moral anchor for believers.
That question is not unlike the stupid Commie test with the flower left to live or die on its own in a room without its normal support system in place that is present in its natural habitat.
God does not grant frivolous favors, nor perhaps does he even bother acknowledging their existence, and the answers he does give we may not like, but they serve a higher purpose that may not be revealed until we are ready to see it.
