1Cor.14.9

So if you speak in a way no one can understand, what's the point of opening your mouth?

1Cor.14.9

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.

1Cor.14.9

So likewise you, unless you utter by the tongue words easy to understand, how will it be known what is spoken? For you will be speaking into the air.

1Cor.14.9

And it's the same for you. If you talk to people in a language they don't understand, how will they know what you mean? You might as well be talking to an empty room.
