13For this reason the one who speaks in a tongue should pray that they may interpret what they say. 14For if I pray in a tongue, my spirit prays, but my mind is unfruitful. 15So what shall I do? I will pray with my spirit, but I will also pray with my understanding; I will sing with my spirit, but I will also sing with my understanding. 16Otherwise when you are praising God in the Spirit, how can someone else, who is now put in the position of an inquirer, The Greek word for inquirer is a technical term for someone not fully initiated into a religion; also in verses 23 and 24. say “Amen” to your thanksgiving, since they do not know what you are saying?
17You are giving thanks well enough, but no one else is edified.
