⁶ Now, brothers and sisters, if I come to you and speak in tongues, what good will I be to you, unless I bring you some revelation or knowledge or prophecy or word of instruction? ⁷ Even in the case of lifeless things that make sounds, such as the pipe or harp, how will anyone know what tune is being played unless there is a distinction in the notes? ⁸ Again, if the trumpet does not sound a clear call, who will get ready for battle? ⁹ So it is with you. Unless you speak intelligible words with your tongue, how will anyone know what you are saying? You will just be speaking into the air. ¹⁰ Undoubtedly there are all sorts of languages in the world, yet none of them is without meaning. ¹¹ If then I do not grasp the meaning of what someone is saying, I am a foreigner to the speaker, and the speaker is a foreigner to me. ¹² So it is with you. Since you are eager for gifts of the Spirit, try to excel in those that build up the church.

    ¹³ For this reason those who speak in a tongue should pray that they may interpret what they say. ¹⁴ For if I pray in a tongue, my spirit prays, but my mind is unfruitful. ¹⁵ So what shall I do? I will pray with my spirit, but I will also pray with my understanding; I will sing with my spirit, but I will also sing with my understanding. ¹⁶ Otherwise when you are praising God in the Spirit, how can the others, who are now put in the same situation as an inquirer, ^[d] say “Amen” to your thanksgiving, since they do not know what you are saying? ¹⁷ You are giving thanks well enough, but the others are not edified.

    ¹⁸ I thank God that I speak in tongues more than all of you. ¹⁹ But in the church I would rather speak five intelligible words to instruct others than ten thousand words in a tongue.

    ²⁰ Brothers and sisters, stop thinking like children. In regard to evil be infants, but in your thinking be adults. ²¹ In the Law it is written:
       “With other tongues
       and through the lips of foreigners
       I will speak to this people,
       but even then they will not listen to me,
       says the Lord.” ^[e]

    ²² Tongues, then, are a sign, not for believers but for unbelievers; prophecy, however, is not for unbelievers but for believers. ²³ So if the whole church comes together and everyone speaks in tongues, and inquirers or unbelievers come in, will they not say that you are out of your mind? ²⁴ But if an unbeliever or an inquirer comes in while everyone is prophesying, they are convicted of sin and are brought under judgment by all, ²⁵ as the secrets of their hearts are laid bare. So they will fall down and worship God, exclaiming, “God is really among you!”   

²⁶ What then shall we say, brothers and sisters? When you come together, each of you has a hymn, or a word of instruction, a revelation, a tongue or an interpretation. Everything must be done so that the church may be built up. ²⁷ If anyone speaks in a tongue, two—or at the most three—should speak, one at a time, and someone must interpret. ²⁸ If there is no interpreter, the speaker should keep quiet in the church; let them speak to themselves and to God.

    ²⁹ Two or three prophets should speak, and the others should weigh carefully what is said. ³⁰ And if a revelation comes to someone who is sitting down, the first speaker should stop. ³¹ For you can all prophesy in turn so that everyone may be instructed and encouraged. ³² The spirits of prophets are subject to the control of prophets. ³³ For God is not a God of disorder but of peace—as in all the congregations of the Lord’s people.” 1 Corinthian 14:1-33    

“… the LORD answered me, and said, Write the vision, and make it plain upon tables, that he may run that readeth it.”
Habbkuh  2:2

If God wanted to he could  get the rocks to speak out (we see this today when we use a cassette tape, it’s coated with iron oxide which comes from a rock.)
 

“I tell you that, if these should hold their peace, the stones would immediately cry out.”
Luke 19:40

So what is the difference between a person prophecying and a prophet?

So what is a Prophet?

And He said, Hear now my words: If there be a prophet among you, I the Lord will make myself known unto him in a vision, and will speak to him in a dream. My servant Moses is not so, who is faithful in all mine house. With him I will speak mouth to mouth….Numbers 12: 6-8

  ”It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God”  Matthew 4:4

  Think not that I have come to destroy the law , or the prophets; I am not come to destroy, but to fulfill. For verily I say to you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled. Matthew 5: 17-18

Touch not my anointed ones and do my prophets no harm. Psalms 105:15

And so the word of the Lord lives forever….

 22 ”Since you have in obedience to the truth purified your souls for a sincere love of the brethren, fervently love one another from the heart, 23 for you have been born again not of seed which is perishable but imperishable, that is, through the living and enduring word of God. 24 For,  “ALL FLESH IS LIKE GRASS,  AND ALL ITS GLORY LIKE THE FLOWER OF GRASS.  THE GRASS WITHERS,  AND THE FLOWER FALLS OFF, 25 BUT THE WORD OF THE LORD ENDURES FOREVER.”  And this is the word which was preached to you. ”1st Peter 1:22-25

This website, Prophetic Office Calling, does a really good job of explaining the difference between the Office of the Prophet and the Prophetic Ministry. It will give you additional insight and explain how it fits in context with the other gifts.

The Voice Magazine Online features an interview with Graham Cooke in which he is asked many questions about prophecy and the prophetic ministry that you too may be wondering about. Also, there’s free downloads, a ministry directory, books, and other resources you can check out.

IHop resources regarding prophecy.

 Books:

Note, I haven’t read all these books (except for Graham Cooke’s book which is excellent), but I have checked out the reviews, and they seem like they would be good ones. If  you’re interested you can check them out further yourself.
