1 Corinthians 14:5-9

I would be delighted if you all spoke in tongues, but I desire even more that you impart prophetic revelation to others. Greater gain comes through the one who prophesies than the one who speaks in tongues, unless there is interpretation so that it builds up the entire church. My dear friends, what good is it if I come to you always speaking in tongues? But if I come with a clear revelation from God, or with insight, or with a prophecy, or with a clear teaching, I can enrich you. Similarly, if musical instruments, such as flutes or stringed instruments, are out of tune and don’t play the arrangement clearly, how will anyone recognize the melody? If the bugle makes a garbled sound, who will recognize the signal to show up for the battle? So it is with you. Unless you speak in a language that’s easily understood, how will anyone know what you’re talking about? You might as well save your breath!
