Paul exhorts us to greet one another with “a psalm, a hymn, or a spiritual song.”  He is telling us to always be ready with fresh manna, the fresh word of God.  In this sense each of God’s people is called to become a prophet of the Most High.  A “prophet” is one who “speaks forth” the word of God.  He is one who is, one who has learned to rest, to be, in the presence of God.

But, how does one ever come to the place where he believes that he can speak forth the word of God?  He sits each day at God’s door.  He does not sit in the seat of sinners and carouse with them.  He does not laugh at the dirty jokes of the one he thinks superior to himself.  She does not smile at the flirtatious innuendo of the colleague that can better her career.   No, the one who would please God learns and understands that “the totality of God’s Word is truth” and begins to bring his understanding of the world, his or her paradigm of reality, into alignment with that truth.

Blessed is the man that hears me, Watching daily at my gates, Waiting at the posts of my doors. (Proverbs 8:34 ASV)

This is the prophet.  And this is why the words of the prophet are prophetic.
