The Word of God

How can it be logically explained that any Divine book could satisfactorily address the ethnic and parochial problems of all mankind alike? Add to this the claim of universality and the probability will increase manifold. But all such questions would be put to only that book which, besides claiming being Divine, is found in its original and pure form. So the first and foremost question to be dealt with is about the status of purity and originality of a Divine book. How a book can dispel the doubts of its followers which itself harbours in doubts? How a book can lead its followers to the path of certainty when its own status is uncertain? Can such a book be trusted to guide human being to the right path that might have once carried the Divine message but had been proved altered afterwards? Can a book be regarded trustworthy enough to guard its followers against the onslaughts of Satan that could not guard itself? Owing to the influence of Satan it could rather deviate the followers from the right path.
