1 Corinthians 14:7-11

7Even lifeless instruments like the flute or the harp must play the notes clearly, or no one will recognize the melody.

8And if the bugler doesn’t sound a clear call, how will the soldiers know they are being called to battle?

9It’s the same for you. If you speak to people in words they don’t understand, how will they know what you are saying? You might as well be talking into empty space.

10There are many different languages in the world, and every language has meaning.

11But if I don’t understand a language, I will be a foreigner to someone who speaks it, and the one who speaks it will be a foreigner to me.
