12 So it is with you. Since you are eager for gifts of the Spirit, try to excel in those that build up the church.
13 For this reason the one who speaks in a tongue should pray that they may interpret what they say. 14 For if I pray in a tongue, my spirit prays, but my mind is unfruitful. 15 So 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.
