8. And if a trumpet call is unrecognizable, then who will prepare for battle?
9. It’s the same way with you: If you don’t use language that is easy to understand when you speak in a tongue, then how will anyone understand what is said?
10. It will be as if you are speaking into the air! There are probably many language families in the world, and none of them are without meaning.
11. So if I don’t know the meaning of the language, then I will be like a foreigner to those who speak it, and they will be like foreigners to me.
12. The same holds true for you: since you are ambitious for spiritual gifts, use your ambition to try to work toward being the best at building up the church.
13. Therefore, those who speak in a tongue should pray to be able to interpret.
14. If I pray in a tongue, my spirit prays but my mind isn’t productive.
15. What should I do? I’ll pray in the Spirit, but I’ll pray with my mind too; I’ll sing a psalm in the Spirit, but I’ll sing the psalm with my mind too.
