Prophecies given by God are accurate – 100% of the time. In the Old Testament, it was a position God gave you to be a prophet. If He wanted to move in someone, He did. And when He did, it was with specificity and boldness. God knows all and is everywhere, so when He spoke through a prophet, you could be sure it was true.  You don't see prophecy today like in the Old Testament, but there is a gift of prophecy from the Holy Spirit. As you'll get to see today with Pastor Mark, God can speak into your heart things that you can know for certain are true. That's why there aren't prophets now – everyone can be led by God and hear from Him directly.
