John 16:13. When the Spirit of truth comes, he will guide you into all the truth, for he will not speak on his own authority, but whatever he hears he will speak, and he will declare to you THE THINGS THAT ARE TO COME. ….
As far as the greater sense of prophecy is concerned, the revelation of God is complete in the Scripture. That is, no teacher can claim that the Spirit says some new truth to him that is different from what Jesus said because the Spirit will only speak what He hears from Jesus. John 16:14. Eg. Jesus said that those whom He loves, He will rebuke and discipline. Rev 3:19. So any teacher who claim a new truth from the Spirit of Jesus that He will not convict or rebuke a Christian of sin is a false teacher.
But in the lesser sense of prophecy, it is still God’s sovereignty today to use whoever He wants to tell some future event to prepare His people. Eg Acts 11:27-30. It was noteworthy to know that the Antioch church acted on the prophecy to prepare and send relief to help the church in Judea through Paul and Barnabas. And the leaders in Jerusalem were humble to receive them.
It is important to note that Scripture exhorts us NOT to despise prophecy but to test all of them. 1 Thess 5:20.
