9 In the same way, how will anyone understand what you are talking about if your message given in strange tongues is not clear? Your words will vanish in the air!
10 There are many different languages in the world, yet none of them is without meaning.
11 But if I do not know the language being spoken, those who use it will be foreigners to me and I will be a foreigner to them.
12 Since you are eager to have the gifts of the Spirit, you must try above everything else to make greater use of those which help to build up the church.
13 The person who speaks in strange tongues, then, must pray for the gift to explain what is said.
14 For if I pray in this way, my spirit prays indeed, but my mind has no part in it.
15 What should I do, then? I will pray with my spirit, but I will pray also with my mind; I will sing with my spirit, but I will sing also with my mind.
