Let me put forth a few propositions. If there is a book written by God, it must first of all mention God. It must tell you that it is from God and that its author is God. This is the first qualification. Second, it must carry a moral tone that is higher than what we commonly know. If it is a fabrication, it can at the most be on the same level as man. Third, if there is such a divine book, it must tell us about the past and the future of this world. Only God knows clearly what occurred in the past and what will happen in the future. Only by telling us these matters will we know Him as God. Fourth, this book must be simple and available so that all may be able to secure and understand it. If there were only one such book in the world, then only a very few people would be able to see it. It would not pass the test unless it is a book accessible to everyone. In the United States there is a group of people who claim to have a book from God. It is engraved in gold and contains only twelve pages. Such a book then would not be accessible to the Chinese. God would never write to us a book at which we could not look.
Now the matter is simplified. Let us repeat these four conditions once more. (1) If such a book exists, it must tell us explicitly that its author is God. (2) It must carry a high tone of morality. (3) It must give a detailed description of the past and the future of the universe. (4) It must be available. Let us pick out some of the more important writings throughout human civilization and check them against these qualifications to see if any meets our requirements.
We will start from books that are generally considered to be good. Let us take the Chinese classics of Confucius. They are immediately disqualified under the first requirement, for none of them claims to be written by God. They do have a high tone of morality, but they fail to give the origin and destiny of the world, the universe, and man. This does not mean that they are worthless books; it means that they do not contain the qualifications we want. They are not what we are looking for.
Let us go to the classics of other cultures. There are numerous volumes of famous writings, but none of them passes the first test. They are all clearly written by man. They may be masterpieces in philosophy or morality, but they are not written by God, nor are they divinely inspired. We have to set them aside.
There is a book in India called the Rig-Veda. It once dominated Hinduism. However, it does not claim to be written by God.
Another book called the Avesta, written by a Persian named Zoroaster, is also extremely influential in the Middle East. It does not claim to be from God either. Moreover, its moral tone is not especially commendable.
Let us come to the Koran of Mohammedanism. This is the closest one we can find. It tells us that it comes from God; it meets the first requirement. However, it does not fulfill the second requirement, for its moral tone is too low. The heaven it describes is full of lusts and flesh. God could never write a book with such licentiousness and immorality. Hence, this book does not pass the test of morality.
