3 But when you prophesy, you will be understood, and others will be helped. They will be encouraged and made to feel better.
4 By speaking languages that others don't know, you help only yourself. But by prophesying you help everyone in the church.
5 I am glad for you to speak unknown languages, although I prefer that you would prophesy. In fact, prophesying does much more good than speaking unknown languages, unless someone can help the church by explaining what you mean.
6 My friends, what good would it do, if I came and spoke unknown languages to you and didn't explain what I meant? How would I help you, unless I told you what God had shown me or gave you some knowledge or prophecy or teaching?
7 If all musical instruments sounded alike, how would you know the difference between a flute and a harp?
8 If a bugle call isn't clear, how would you know to get ready for battle?
9 This is how it is when you speak unknown languages. If no one can understand what you are talking about, you will only be talking to the wind.
