1 Corinthians 14:13-19

So then, if you speak in a tongue, pray for the interpretation to be able to unfold the meaning of what you are saying. For if I am praying in a tongue, my spirit is engaged in prayer but I have no clear understanding of what is being said. So here’s what I’ve concluded. I will pray in the Spirit, but I will also pray with my mind engaged. I will sing rapturous praises in the Spirit, but I will also sing with my mind engaged. Otherwise, if you are praising God in your spirit, how could someone without the gift participate by adding his “amen” to your giving of thanks, since he doesn’t have a clue of what you’re saying? Your praise to God is admirable, but it does nothing to strengthen and build up others. I give thanks to God that I speak in tongues more than all of you, but in the church setting I would rather speak five words that can be understood than ten thousand exotic words in a tongue. That way I could have a role in teaching others.
