Prophesying in an ecstatic utterance because of the outpouring of the Spirit, prophesying of things to come, prophesying as in exposing the secrets of a mans heart and causing them to believe that God is in you of a truth, prophesying on a street corner speaking like a "prophet" from God with a message for heaven or in a church service warning of a famine, and even speaking in tongues with an interpretation which is as good as prophecy according to Paul.
