15. So what should I do? I will pray with my spirit, but I will also pray with my mind. I will sing with my spirit, but I will also sing with my mind.
16. You might be praising God with your spirit. But someone there without understanding cannot say “Amen” to your prayer of thanks, because they don’t know what you are saying.
17. You may be thanking God in a good way, but others are not helped.
18. I thank God that my gift of speaking in different kinds of languages is greater than any of yours.
19. But in the church meetings I would rather speak five words that I understand than thousands of words in a different language. I would rather speak with my understanding, so that I can teach others.
20. Brothers and sisters, don’t think like children. In evil things be like babies, but in your thinking you should be like full-grown adults.
21. As the Scriptures say, “Using those who speak a different language and using the lips of foreigners, I will speak to these people. But even then, they will not obey me.” Isaiah 28:11-12 This is what the Lord says.
22. And from this we see that the use of different languages shows how God deals with those who don’t believe, not with those who believe. And prophecy shows how God works through those who believe, not through unbelievers.
23. Suppose the whole church meets together and you all speak in different languages. If some people come in who are without understanding or don’t believe, they will say you are crazy.
