6 After all, brothers and sisters, if I come to you speaking in tongues, how will I help you unless I speak to you with a revelation, some knowledge, a prophecy, or a teaching?
7 Likewise, things that aren’t alive like a harp or a lyre can make a sound, but if there aren’t different notes in the sounds they make, how will the tune from the harp or the lyre be recognized?
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.
