Covet spiritual gifts. Lest the Corinthians should object that they wronged God, if they despised his gifts, the Apostle anticipates this objection by declaring, that it was not his design to draw them away even from those gifts that they had abused -- nay rather he commends the pursuit of them, and wishes them to have a place in the Church. And assuredly, as they had been conferred for the advantage of the Church, man's abuse of them ought not to give occasion for their being thrown away as useless or injurious, but in the meantime he commends prophecy above all other gifts, as it was the most useful of them all. He observes, therefore, an admirable medium, by disapproving of nothing that was useful, while at the same time he exhorts them not to prefer, by an absurd zeal, things of less consequence to what was of primary importance. Now he assigns the first place to prophecy. Covet, therefore, spiritual gifts -- that is, "Neglect no gift, for I exhort you to seek after them all, provided only prophecy holds the first place."

Follow after charity - Pursue love 1-Corinthians 13:1; that is, earnestly desire it; strive to possess it; make it the object of your anxious and constant solicitude to obtain it, and to be influenced by it always. Cultivate it in your own hearts, as the richest and best endowment of the Holy Spirit, and endeavor to diffuse its happy influence on all around you.
And desire spiritual gifts - I do not forbid you, while you make the possession of love your great object, and while you do not make the desire of spiritual gifts the occasion of envy or strife, to desire the miraculous endowments of the Spirit and to seek to excel in those endowments which he imparts; see the note at 1-Corinthians 12:31. The main thing was to cultivate a spirit of love. Yet it was not improper also to desire to be so endowed as to promote their highest usefulness in the church. On the phrase "spiritual gifts," see the note at 1-Corinthians 12:1.
But rather that ye may prophesy - But especially, or particularly desire to be qualified for the office of prophesying. The apostle does not mean to say that prophecy is to be preferred to love or charity; but that, of the spiritual gifts which it was proper for them to desire and seek, prophecy was the most valuable. That is, they were not most earnestly and especially to desire to be able to speak foreign languages or to work miracles; but they were to desire to be qualified to speak in a manner that would be edifying to the church. They would naturally, perhaps, most highly prize the power of working miracles and of speaking foreign languages. The object of this chapter is to show them that the ability to speak in a plain, clear, instructive manner, so as to edify the church and convince sinners, was a more valuable endowment than the power of working miracles, or the power of speaking foreign languages.
On the meaning of the word "prophesy," see the note at Romans 11:6. To what is said there on the nature of this office, it seems necessary only to add an idea suggested by Prof. Robinson (Greek and English Lexicon, under the article, Προφήτης Prophētēs), that the prophets were distinguished from the teachers (διδάσκαλοι didaskaloi), "in that, while the latter spoke in a calm, connected, didactic discourse adapted to instruct and enlighten the hearers, the prophet spoke more from the impulse of sudden inspiration, from the light of a sudden revelation at the moment (1-Corinthians 14:30, ἀποκάλυφθη apokalupthē), and his discourse was probably more adapted, by means of powerful exhortation, to awaken the feelings and conscience of the hearers." The idea of speaking from "revelation," he adds, seems to be fundamental to the correct idea of the nature of the prophecy here referred to. Yet the communications of the prophets were always in the vernacular tongue, and were always in intelligible language, and in this respect different from the endowments of those who spoke foreign languages.
The same truth might be spoken by both; the influence of the Spirit was equally necessary in both; both were inspired; and both answered important ends in the establishment and edification of the church. The gift of tongues, however, as it was the most striking and remarkable, and probably the most rare, was most highly prized and coveted. The object of Paul here is, to show that it was really an endowment of less value, and should be less desired by Christians than the gift of prophetic instruction, or the ability to edify the church in language intelligible and understood by all, under the immediate influences of the Holy Spirit.

Follow after charity - Most earnestly labor to be put in possession of that love which beareth, believeth, hopeth, and endureth all things. It may be difficult to acquire, and difficult to retain this blessed state, but it is essential to your present peace and eternal happiness. This clause belongs to the preceding chapter.
Desire spiritual gifts - Ye are very intent on getting those splendid gifts which may add to your worldly consequence, and please your carnal minds - but labor rather to get the gifts of God's Spirit, by which ye may grow in grace, and be useful to others - and particularly desire that ye may prophesy - that ye may be able to teach and instruct others in the things of their salvation.

Follow (1) after charity, and desire spiritual [gifts], but rather that ye may (a) prophesy.
(1) He infers now of what he spoke before: therefore seeing charity is the chiefest of all, before all things set it before you as chief and principal. And so esteem those things as most excellent which profit the greater part of men (such as prophecy, that is to say, the gift of teaching and applying the doctrine: which was condemned in respect of other gifts, although it is the chiefest and most necessary for the Church) and not those who for a show seem to be marvellous, as the gifts of tongues. This was when a man was suddenly endowed with the knowledge of many tongues, which made men greatly amazed and yet of itself was not greatly of any use, unless there was an interpreter.
(a) What prophecy is he shows in the third verse.

Follow after charity,.... The apostle having so highly commended charity, or love, in the preceding chapter, presses here to an eager pursuit after it; that is, to an exercise of it, and after those things which make for it, and will serve to maintain and increase it: and everything he has said in praise of it before serves as an argument, or reason, to follow hard after it, with an eagerness used in hunting, and with such violence as persecutors express in pursuing and laying hold on those they seek after, to which there is an allusion in the word here used:
and desire spiritual gifts: for though he had given charity the preference to them, he did not mean that they should despise and neglect them, or treat them with indifference, and be unconcerned about them; but, on the other hand, that they should be very zealous for them, ambitious of them, and earnestly covet them; since being rightly used and kept in their proper place, they were greatly beneficial and profitable to the churches of Christ, and the glory of God:
but rather that ye may prophesy: of all the gifts of the Spirit, the apostle prefers prophesying, and recommends this to the Corinthians, as what they should be chiefly desirous of, and more desirous of than of speaking with tongues, which many among them were so very fond of: by which he means, not so much the gift of foretelling future events, though there was such a gift bestowed on some persons in those times, and, in certain cases, was very profitable to the churches; but a gift of preaching the word, or explaining the prophecies of the Old Testament, and of praying and singing of psalms, all which, as appears from some following parts of this chapter, were included in it; and that not in an ordinary, but in an extraordinary way; a person possessed of this gift could at once, without the use of means, or help of study, preach the word, and open the more difficult parts of Scripture; he had an extraordinary gift of prayer, which he could make use of when he pleased, and at once compose and deliver out a psalm, or hymn, in the public congregation.

Prophesying, that is, explaining Scripture, is compared with speaking with tongues. This drew attention, more than the plain interpretation of Scripture; it gratified pride more, but promoted the purposes of Christian charity less; it would not equally do good to the souls of men. What cannot be understood, never can edify. No advantage can be reaped from the most excellent discourses, if delivered in language such as the hearers cannot speak or understand. Every ability or possession is valuable in proportion to its usefulness. Even fervent, spiritual affection must be governed by the exercise of the understanding, else men will disgrace the truths they profess to promote.

SUPERIORITY OF PROPHECY OVER TONGUES. (1Co. 14:1-25)
Follow after charity--as your first and chief aim, seeing that it is "the greatest" (1-Corinthians 13:13).
and desire--Translate, "Yet (as a secondary aim) desire zealously (see on 1-Corinthians 12:31) spiritual gifts."
but rather--"but chiefly that ye may prophesy" (speak and exhort under inspiration) (Proverbs 29:18; Acts 13:1; 1-Thessalonians 5:20), whether as to future events, that is, strict prophecy, or explaining obscure parts of Scripture, especially the prophetical Scriptures or illustrating and setting forth questions of Christian doctrine and practice. Our modern preaching is the successor of prophecy, but without the inspiration. Desire zealously this (prophecy) more than any other spiritual gift; or in preference to "tongues" (1-Corinthians 14:2, &c.) [BENGEL].

Desire earnestly spiritual gifts. Though love is to be a supreme pursuit, yet this is not intended to disparage spiritual gifts. Let them be sought, but in seeking, desire above all the gift of prophecy.
For he that speaketh in a tongue. Hath the gift of tongues. The tenor of Paul's remarks shows that the Corinthians placed too high a comparative estimate on this gift.
Speaketh mysteries. Things that are unknown and mysterious to his hearers. Men do not understand him.
He that prophesieth. To prophesy means more than to foretell. It is to declare the will of God under a divine impulse. When Peter spoke on Pentecost, he did the work of a New Testament prophet. In this formative period of the church, before the New Testament was written, it was needful that there be these inspired guides in the churches.
Unto men edification. Instruction, and strengthening.
He that speaketh in a tongue edifieth himself. His speech in the unknown tongue tends to strengthen him, though not instructing others. He is made to feel that he is moved by God, and so is filled with awe.
Greater is he that prophesieth. Greater, because he serves the church best. Unless the tongues were interpreted, they were an unmeaning sound to the church, while he who prophesied, instructed and built it up.

Follow after love - With zeal, vigour, courage, patience; else you can neither attain nor keep it. And - In their place, as subservient to this. Desire spiritual gifts; but especially that ye may prophesy - The word here does not mean foretelling things to come; but rather opening and applying the scripture.
