1 Corinthians 14:2-15

I will explain why. Those who have the gift of speaking in different languages are not speaking to people; they are speaking to God. No one understands them; they are speaking secret things through the Spirit. But those who prophesy are speaking to people to give them strength, encouragement, and comfort. The ones who speak in different languages are helping only themselves, but those who prophesy are helping the whole church. I wish all of you had the gift of speaking in different kinds of languages, but more, I wish you would prophesy. Those who prophesy are greater than those who can only speak in different languages—unless someone is there who can explain what is said so that the whole church can be helped. Brothers and sisters, will it help you if I come to you speaking in different languages? No! It will help you only if I bring you a new truth or some new knowledge, or prophecy, or teaching. It is the same as with lifeless things that make sounds—like a flute or a harp. If they do not make clear musical notes, you will not know what is being played. And in a war, if the trumpet does not give a clear sound, who will prepare for battle? It is the same with you. Unless you speak clearly with your tongue, no one can understand what you are saying. You will be talking into the air! It may be true that there are all kinds of sounds in the world, and none is without meaning. But unless I understand the meaning of what someone says to me, we will be like foreigners to each other. It is the same with you. Since you want spiritual gifts very much, seek most of all to have the gifts that help the church grow stronger. The one who has the gift of speaking in a different language should pray for the gift to interpret what is spoken. If I pray in a different language, my spirit is praying, but my mind does nothing. So what should I do? I will pray with my spirit, but I will also pray with my mind. I will sing with my spirit, but I will also sing with my mind.
