Lecture 2 — Tongues’ meaning variable

Now I want you all to speak in tongues, but even more to prophesy. He who prophesies is greater than he who speaks in tongues, unless some one interprets, so that the church may be edified.

Now, brethren, if I come to you speaking in tongues, how shall I benefit you unless I bring you some revelation or knowledge or prophecy or teaching?

If even lifeless instruments, such as the flute or the harp, do not give distinct notes, how will any one know what is played?

And if the bugle gives an indistinct sound, who will get ready for battle?

So with yourselves; if you in a tongue utter speech that is not intelligible, how will any one know what is said? For you will be speaking into the air.

There are doubtless many different languages in the world, and none is without meaning;

but if I do not know the meaning of the language, I shall be a foreigner to the speaker and the speaker a foreigner to me.

So with yourselves; since you are eager for manifestations of the Spirit, strive to excel in building up the church.
