I am what you might call a partial cessationist. That is, while I do not believe the gift of Capital T Tongues is still around, I do believe God gifts certain people in languages - my brother, for one. While I do not believe there are any Capital P Prophets around anymore, I do believe God gifts ministers and teachers with the gifts of little p prophecy. Same goes for Apostles. Why do I believe this? Because the apostles and prophets, the Bible says, are the
foundation of the church. You can't lay a foundation again, only once. Then you build on it. Once you build, you don't lay the foundation again.
As for any prophets, we have the biblical test: if what they say comes true (and this needs to be absolutely, positively, every single time they preface their prophecy with "Thus says the Lord"), then we pay attention to them. But they still can never go against the Bible. God is a God of order, and not of confusion. He will never contradict Himself. Any "prophet" who says anything contrary to Scripture is
ipso facto a false prophet.
The Babylon Bee has a
good one on this. For those who don't know, the Babylon Bee provides Onion-like news articles on the Christian world. They're often extremely funny.
