Modern Day Prophets ARE False Prophets!
Many people today whether they realize it or not are part of something called the New Apostolic Reformation or NAR. This particular movement believes that the office of Apostle and the office of Prophet has been re-established. The Bible sets out very specific criteria for both of these offices. None of which can be met today.
None of the biggest names in the prophetic movement prophesied any of the biggest and most consequential events in all of our lifetimes; they were all spectacularly wrong. They didn't prophesy about covid-19, the presidential election, the riots, or anything else of any consequence. What they prophesied on they got wrong. They should be very glad we do not live in the Old Testament time frame.
