If the very text, upon which your belief system is founded, is untrustworthy, then what can you be certain of your belief system? Randomly praying to a god based on uncertain texts are meaningless, as well as useless. One might as well "pray" to a flying pasta monster in Jupiter orbit.

If "God" can be so easily accessed to an average human, then the numberless factions killing each other across time and space would not be. Personal revelation regarding the divine is nothing more than personal whim excused as "divine commandment." Organising one's life based on personal revelation, or interpretation, of the divine is no different from orgainsing one's life based on feelings. At least the atheist rejects the bronze-age mythology without apology; the modern-day heretic clings on to psychological crutch to justify his whims.
