Prophecies must be judged according to God's word. The revealed word of God is the yardstick to determine the validity of a prophecy. The believer is not expected to be looking for prophets because we all have the Holy Spirit who will teach us all we ought to. (1Peter 1:25; Romans 8:14)
You too can have the spiritual gift of prophecy.
There are no prophets today. Just as there are no miraculous signs, wonders, and healings today.
