21 It's written in Scripture that God said, In strange tongues and from the mouths of strangers I will preach to this people, but they'll neither listen nor believe. 22 So where does it get you, all this speaking in tongues no one understands? It doesn't help believers, and it only gives unbelievers something to gawk at. Plain truth-speaking, on the other hand, goes straight to the heart of believers and doesn't get in the way of unbelievers. 23 If you come together as a congregation and some unbelieving outsiders walk in on you as you're all praying in tongues, unintelligible to each other and to them, won't they assume you've taken leave of your senses and get out of there as fast as they can? 24 But if some unbelieving outsiders walk in on a service where people are speaking out God's truth, the plain words will bring them up against the truth 25 and probe their hearts. Before you know it, they're going to be on their faces before God, recognizing that God is among you.

26 So here's what I want you to do. When you gather for worship, each one of you be prepared with something that will be useful for all: Sing a hymn, teach a lesson, tell a story, lead a prayer, provide an insight. 27 If prayers are offered in tongues, two or three's the limit, and then only if someone is present who can interpret what you're saying. 28 Otherwise, keep it between God and yourself. 29 And no more than two or three speakers at a meeting, with the rest of you listening and taking it to heart. 30 Take your turn, no one person taking over. 31 Then each speaker gets a chance to say something special from God, and you all learn from each other. 32 If you choose to speak, you're also responsible for how and when you speak. 33 When we worship the right way, God doesn't stir us up into confusion; he brings us into harmony. This goes for all the churches - no exceptions.

34 Wives must not disrupt worship, talking when they should be listening, 35 asking questions that could more appropriately be asked of their husbands at home. God's Book of the law guides our manners and customs here. Wives have no license to use the time of worship for unwarranted speaking.

36 Do you - both women and men - imagine that you're a sacred oracle determining what's right and wrong? Do you think everything revolves around you? 37 If any one of you thinks God has something for you to say or has inspired you to do something, pay close attention to what I have written. This is the way the Master wants it. 38 If you won't play by these rules, God can't use you. Sorry. 39 Three things, then, to sum this up: When you speak forth God's truth, speak your heart out. Don't tell people how they should or shouldn't pray when they're praying in tongues that you don't understand. 40 Be courteous and considerate in everything.

Commentary on 1 Corinthians 14:15-25

(Read 1 Corinthians 14:15-25)

There can be no assent to prayers that are not understood. A truly Christian minister will seek much more to do spiritual good to men's souls, than to get the greatest applause to himself. This is proving himself the servant of Christ. Children are apt to be struck with novelty; but do not act like them. Christians should be like children, void of guile and malice; yet they should not be unskilful as to the word of righteousness, but only as to the arts of mischief. It is a proof that a people are forsaken of God, when he gives them up to the rule of those who teach them to worship in another language. They can never be benefitted by such teaching. Yet thus the preachers did who delivered their instructions in an unknown tongue. Would it not make Christianity ridiculous to a heathen, to hear the ministers pray or preach in a language which neither he nor the assembly understood? But if those who minister, plainly interpret Scripture, or preach the great truths and rules of the gospel, a heathen or unlearned person might become a convert to Christianity. His conscience might be touched, the secrets of his heart might be revealed to him, and so he might be brought to confess his guilt, and to own that God was present in the assembly. Scripture truth, plainly and duly taught, has a wonderful power to awaken the conscience and touch the heart.

Commentary on 1 Corinthians 14:26-33

(Read 1 Corinthians 14:26-33)

Religious exercises in public assemblies should have this view; Let all be done to edifying. As to the speaking in an unknown tongue, if another were present who could interpret, two miraculous gifts might be exercised at once, and thereby the church be edified, and the faith of the hearers confirmed at the same time. As to prophesying, two or three only should speak at one meeting, and this one after the other, not all at once. The man who is inspired by the Spirit of God will observe order and decency in delivering his revelations. God never teaches men to neglect their duties, or to act in any way unbecoming their age or station.

Commentary on 1 Corinthians 14:34-40

(Read 1 Corinthians 14:34-40)

When the apostle exhorts Christian women to seek information on religious subjects from their husbands at home, it shows that believing families ought to assemble for promoting spiritual knowledge. The Spirit of Christ can never contradict itself; and if their revelations are against those of the apostle, they do not come from the same Spirit. The way to keep peace, truth, and order in the church, is to seek that which is good for it, to bear with that which is not hurtful to its welfare, and to keep up good behaviour, order, and decency.
