Did all the prophecies in the book come true?
Yes, all the prophecies in the book have come true. Those not yet fulfilled are about to come true, as the handwriting on the wall indicates. The Word of God is absolute and true, so we can rest on it with certainty.
Les explains that the book contains so much prophecy that foretold events hundreds of years in advance, thousands of years in advance, and it has all come true. Everything that hasn't come true yet—we can already see the handwriting on the wall; it is about to. If that much is truth, then why can't it all be true? Well, it is. So when we contemplate these things, we just rest on the word of God as being absolute. It is true, as sure as anything can be, and we can rest on it.
