If you have interest in the true meaning of the Bible, and the meaning behind the prophecies – in terms of dating – you really need to read the books:
It is said you will not know the time, but that is because the ancients knew that, when you are told, you would not pay attention.
Of course, the message will not be accompanied by great fanfare, or an intensive advertising campaigns. The reason those who received the message of their ignorance would be ignorant? It is simply that they will not accept anything which is simple and straight forward. They need the hype. They the charlatans promoting the ancient deities with a coat of new paint … the same thing, with different names.
