13 The one who has the gift of speaking in a different language should pray that he can also interpret what he says.
14 If I pray in a different language, my spirit is praying, but my mind does nothing.
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 a person there without understanding cannot say “Amen” to your prayer of thanks. He does not know what you are saying.
17 You may be thanking God in a good way, but the other person is 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.
