One of the arguments used by religious people to support the Bible is that the Old Testament makes many, many prophecies, most of which come true. Could the Bible be false if all the things it said was going to happen did?
The answer is yes. Most of the prophecies are self-fulfilling, it is easy to fulfill a prophecy if you already know what it says. If a guy knew that there was a prophecy of him riding into a town on a specific horse on a specific day, he would do it and it would seem like a miracle, but he knew of the prophecy, so it really isn’t amazing.
The Bible was written by many people, and the authors of the later books would have gone back to the earlier ones and looked at what was supposed to happen, and then they wrote about the prophecies being fulfilled. Remember that we have few – or no – accounts outside of the Bible for the things that it talks about, meaning that even if a prophecy was said to have been fulfilled, it might not have actually happened. If the Bible predicted that a land would be discovered where America is, then it would seem amazing, because no-one knew of this land and it couldn’t be self-fulfilling. But no, in the Bible we get lots of prophecies that were easy for the people at the time to knowingly fulfill.
Not to mention the fact that there are failed prophecies in the Bible, such as the one saying that the king Nebuchadnezzar would conquer Egypt with chariots – it never happened. And plenty of others haven’t happened. Many say that these prophecies ‘just haven’t happened yet’ like the one about Egypt becoming a wasteland for 40 years, or the one about Tyre being destroyed. But do you really expect the ancient Persian king Nebuchadnezzar to come back to life, build an ancient army of chariots and take over modern day Egypt? Not likely.
