1 Corinthians 14:10-17

14:10 There are probably many kinds of languages in the world, and none is without meaning. 14:11 If then I do not know the meaning of a language, I will be a foreigner to the speaker and the speaker a foreigner to me. 14:12 It is the same with you. Since you are eager for manifestations of the Spirit, seek to abound in order to strengthen the church.

14:13 So then, one who speaks in a tongue should pray that he may interpret. 14:14 If I pray in a tongue, my spirit prays, but my mind is unproductive. 14:15 What should I do? I will pray with my spirit, but I will also pray with my mind. I will sing praises with my spirit, but I will also sing praises with my mind. 14:16 Otherwise, if you are praising God with your spirit, how can someone without the gift say “Amen” to your thanksgiving, since he does not know what you are saying? 14:17 For you are certainly giving thanks well, but the other person is not strengthened.
