1 Corinthians 14

As Paul refers back to the gifs of the Spirit, he obviously  downplays the speaking of tongues while elevating the gift of prophecy.  In my mind, "prophecy" is that which a prophet does.  Most people immediately consider prophecy to be that of foretelling the future.  But even so, the prophets in scripture tend to testify of Jesus Christ and His doctrine.  Scriptural prophets taught truth, refuted falsehoods, reproved as necessary, admonished the people, and provided comfort to them.  This seems more in line with that which Paul counsels the Corinthians writing -

"...he that prophesieth speaketh unto men to edification, and exhortation, and comfort.
4 He that speaketh in an unknown tongue edifieth himself; but he that prophesieth edifieth the church."  (New Testament | 1 Corinthians 14:3 - 4)

Even reasoning -

"...what shall I profit you, except I shall speak to you either by revelation, or by knowledge, or by prophesying, or by doctrine?"  (New Testament | 1 Corinthians 14:6)

And in speaking of Church worship services -

"...Let the prophets speak two or three, and let the other judge."  (New Testament | 1 Corinthians 14:29)

"For ye may all prophesy one by one, that all may learn, and all may be comforted."  (New Testament | 1 Corinthians 14:31)

It is given to all saints that they may prophecy, that is -

"...when ye come together, every one of you hath a psalm, hath a doctrine, hath a tongue, hath a revelation, hath an interpretation. Let all things be done unto edifying."  (New Testament | 1 Corinthians 14:26)

I am reminded of the desire of Moses -

"...would God that all the LORD's people were prophets, and that the LORD would put his spirit upon them!" (Old Testament | Numbers 11:29)

In other words, teach, admonish, comfort and edify.
