[2] For anyone who speaks in a tongue does not speak to people but to God. Indeed, no one understands them; they utter mysteries by the Spirit. [3] But the one who prophesies speaks to people for their strengthening, encouraging and comfort. [4] Anyone who speaks in a tongue edifies themselves, but the one who prophesies edifies the church. [5] I would like every one of you to speak in tongues, but I would rather have you prophesy. The one who prophesies is greater than the one who speaks in tongues, unless someone interprets, so that the church may be edified. [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 or knowledge or prophecy or word of instruction? [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? [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. [12] So it is with you. Since you are eager for gifts of the Spirit, try to excel in those that build up the church.
