2 For he who makes use of tongues is not talking to men but to God; because no one has the sense of what he is saying; but in the Spirit he is talking of secret things. 3 But the word of the prophet gives men knowledge and comfort and strength. 4 He who makes use of tongues may do good to himself; but he who gives the prophet's word does good to the church. 5 Now though it is my desire for you all to have the power of tongues, it would give me more pleasure to be hearing the prophet's word from you; for this is a greater thing than using tongues, if the sense is not given at the same time, for the good of the church.
6 But, now, my brothers, if I come to you using tongues, what profit will it be to you, if I do not give you a revelation, or knowledge, or the word of the prophet, or teaching? 7 Even things without life, having a voice, such as a music-pipe or other instrument, if they do not give out different sounds, who may be certain what is being played? 8 For if the war-horn gives out an uncertain note, who will get ready for the fight? 9 So if you, in using a strange tongue, say words which have no sense, how will anyone take in what you are saying? for you will be talking to the air. 10 There are, it may be, a number of different voices in the world, and no voice is without sense. 11 But if the sense of the voice is not clear to me, I am like a man from a strange country to him who is talking, and he will be the same to me. 12 So if you are desiring the things which the Spirit gives, let your minds be turned first to the things which are for the good of the church.

Commentary on 1 Corinthians 14:1-5
(Read 1 Corinthians 14:1-5)
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.
Commentary on 1 Corinthians 14:6-14
(Read 1 Corinthians 14:6-14)
Even an apostle could not edify, unless he spoke so as to be understood by his hearers. To speak words that have no meaning to those who hear them, is but speaking into the air. That cannot answer the end of speaking, which has no meaning; in this case, speaker and hearers are barbarians to each other. All religious services should be so performed in Christian assemblies, that all may join in, and profit by them. Language plain and easy to be understood, is the most proper for public worship, and other religious exercises. Every true follower of Christ will rather desire to do good to others, than to get a name for learning or fine speaking.
