Christians believe The Bible predicts a bunch of things. I’m yet to see any convincing predictions. Surely God could have made at least a couple crystal clear ones that couldn’t be called into question?
For comparison, let’s look at a modern example of a prophetic work that people believe in: The Simpsons. Take a look to see how these ideas relate next time you are looking at Bible prophecy. Also, look into “self-fulfilling prophecy” – that is a concept that was completely ignored when Bible prophecy was talked about at the church I attended. It is when prophecies come true because people want them to come true and work for them to come true.
