1 Cor. 14:2-5 (NIV) For anyone who speaks in a tongue does not speak to men but to God. Indeed, no one understands him; he utters mysteries with his spirit.  But everyone who prophesies speaks to men for their strengthening, encouragement and comfort.  He who speaks in a tongue edifies himself, but he who prophesies edifies the church.  I would like every one of you to speak in tongues, but I would rather have you prophesy. He who prophesies is greater than one who speaks in tongues, unless he interprets, so that the church may be edified…1 Cor. 14:14-15 (NIV) For if I pray in a tongue, my spirit prays, but my mind is unfruitful.  So what shall I do? I will pray with my spirit, but I will also pray with my mind; I will sing with my spirit, but I will also sing with my mind…1 Cor. 14:39 (NIV) Therefore, my brothers, be eager to prophesy, and do not forbid speaking in tongues.
