1 Corinthians 14:10-15

I suppose that the world has all sorts of languages, and each conveys meaning to the ones who speak it. But I am like a foreigner if I don’t understand the language, and the speaker will be like a foreigner to me. And that’s what’s happening among you. You are so passionate about embracing the manifestations of the Holy Spirit! Now become even more passionate about the things that strengthen the entire church. 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.
