The role of prophets changed during the Pentecost celebration recorded in Acts 2. Previously, they appeared about one per generation or so. They acted with greater authority. They got revelation that ended up being Scripture.
Now, we could expect the numbers to have increased to a typical count being several per congregation. Most don’t know they are prophets, many because they are being misled to believe that there are not prophets around these days.
New testament jobs are not taught in a manual. Some gifts are so unexplained in the Bible that there is not even a person named who did a certain ministry. That is so you will have to ask the Spirit.
Three works prophets do now are – announcing the future (Acts11:28), commanding something to happen (Acts 3:6), and interpreting current events based on something God says, either in written Scripture or by revelation (Acts 15:12-17; Acts 27:21-26).
It is funny that most “Bible prophecy conferences” are hosted by teachers, who teach that there are no prophets in the church today. Further, they are attempting to do prophetic work, interpreting events and announcing the future, with the Spiritual gift of teacher instead of the proper gift, which is prophet.
If you want to know what is gonna happen, or to understand what is happening, pray for some prophets to rise up and grow in the process of learning how to announce and interpret accurately, and how to command with authority.
