⁶ Now, brothers and sisters, if I come to you and speak in tongues, what good will I be to you, unless I bring you some revelation^(A) or knowledge^(B) or prophecy or word of instruction?^{(C) 7} Even in the case of lifeless things that make sounds, such as the pipe or harp, how will anyone know what tune is being played unless there is a distinction in the notes? ⁸ Again, if the trumpet does not sound a clear call, who will get ready for battle?^{(D) 9} So it is with you. Unless you speak intelligible words with your tongue, how will anyone know what you are saying? You will just be speaking into the air. ¹⁰ Undoubtedly there are all sorts of languages in the world, yet none of them is without meaning. ¹¹ If then I do not grasp the meaning of what someone is saying, I am a foreigner to the speaker, and the speaker is a foreigner to me.^{(E) 12} So it is with you. Since you are eager for gifts of the Spirit,^(F) try to excel in those that build up^(G) the church.
