1 Corinthians 14:6-12 New Century Version (NCV)

⁶ 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. ⁷ 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. ⁸ And in a war, if the trumpet does not give a clear sound, who will prepare for battle? ⁹ 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! ¹⁰ It may be true that there are all kinds of sounds in the world, and none is without meaning. ¹¹ But unless I understand the meaning of what someone says to me, we will be like foreigners to each other. ¹² 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.
