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.
24. But suppose you are all prophesying and someone comes in who does not believe or who is without understanding. Their sin will be shown to them, and they will be judged by everything you say.
25. The secret things in their heart will be made known. So they will bow down and worship God. They will say, “Without a doubt, God is here with you.”
26. So, brothers and sisters, what should you do? When you meet together, one person has a song, another has a teaching, and another has a new truth from God. One person speaks in a different language, and another interprets that language. The purpose of whatever you do should be to help everyone grow stronger in faith.
