14. If I pray in another language, my spirit prays, but my mind is not productive.
15. So what does this mean? It means that I will pray with my spirit, and I will pray with my mind. I will sing psalms with my spirit, and I will sing psalms with my mind.
16. Otherwise, if you praise God only with your spirit, how can outsiders say “Amen!” to your prayer of thanksgiving? They don’t know what you’re saying.
17. Your prayer of thanksgiving may be very good, but it doesn’t help other people grow.
18. I thank God that I speak in other languages more than any of you.
19. Yet, in order to teach others in church, I would rather say five words that can be understood than ten thousand words in another language.
