Hebrews 11:32 - "And what more shall I say? For time would fail me to tell of Gideon, Barak, Samson, Jephtah, of David and Samuel and the prophets -"
"Prophet" is the Greek word used in the Greek Old Testament to translate a Hebrew word whose meaning is obscure; the Greek meant a person who spoke or interpreted oracles, and therefore was not speaking his own thoughts, but those of a god. Although the word in essence means "forth-telling," not "fore-telling," still part of the Greek word means "before," and since they considered prophecies and prophetic utterances to deal with future events and foreknowledge, it was not difficult for them to take the next step and consider that the prophetic message was a predictive one. They also felt that a prophet must necessarily speak while in an ecstatic state, so that the god might speak through him. It was this idea of the prophet as giving ecstatic predictions that has colored and misinterpreted our understanding through the centuries.
While it is true, as stated above, that the meaning of the Hebrew word is obscure, the most generally accepted scholarly opinion is that it merely meant "to announce;" but this announcement was on divine order, and so, finally, the prophet was one "who utters a God-given message." This could be, and often was, a prediction of future events, usually a warning of doom if conditions were not improved, but it did not have to be such a message. Whatever it involved, it came directly from God, and it is for this that we remember the prophets - as spokesmen for God.
In this way, we can see that the prophet differs from the priest. While both were communicators, they were on opposite sides of the fence, so to speak - the priest carried the words and petitions of the people to God, while the prophet carried God’s messages to the people.
We have a wide range of individuals in the ranks of the prophets - from the early ecstatics to the sophiscated such as Isaiah; from those who acted out their prophecies to those who were almost fantastically visionary; from those who were specifically ethical to those who were seemingly objective. All of which tells us that God never goes by any man’s rules - he chooses the best and most effective medium at any one time. And certainly the disparity of the prophets is proof of that.
Prophecy, as such, had long disappeared by New Testament times, although we find the use of the term in connection with New Testament men (and women, too). But in the New Testament, it refers to preachers and evangelists; they were Christian teachers to whom the Spirit, at times, made special direct communication and who interpreted God’s will to man.
Today, of course, the pastor or preacher or minister of a congregation fulfills the role of the prophet. In fact, this is one of the specific elements within the call to preach.
