Prophecy like any gift of the Spirit can come in various ways.

The Spirit of God is not limited to man’s forms or religious ideas.   I Cor. 12:1-3.  The Apostle Paul by the Spirit tells us; “not to be ignorant of Spiritual Gifts. They are not dumb Idols; they live and move an have their being in Christ. That no man speaking by the Holy Spirit will curse the Christ living in a brother or sister because we do not use the same delivery, style or technique.

The word itself will testify to the Lordship of Jesus by the inner witness of the Holy Ghost. There are diversities of gifts.  Differences of administering the gifts and diversities of operations of the gifts but it is the same Holy Spirit and the same Lord working all and in all.
