Prophecy Should Edify The Church, 1 Corinthians 14.

Pursue love, and desire spiritual gifts,  but especially that you may prophesy. For he who speaks in a tongue does not speak to men but to God, for no one understands him; however, in the spirit he speaks mysteries. But he who prophesies speaks edification and exhortation and comfort to men. He who speaks in a tongue edifies himself, but he who prophesies edifies the church. I wish you all spoke with tongues, but even more that you prophesied; for he who prophesies is greater than he who speaks with tongues, unless indeed he interprets, that the church may receive edification. So likewise you, unless you utter by the tongue words easy to understand, how will it be known what is spoken? For you will be speaking into the air. There are, it may be, so many kinds of languages in the world, and none of them is without significance. Therefore, if I do not know the meaning of the language, I shall be a foreigner to him who speaks, and he who speaks will be a foreigner to me. Even so you, since you are zealous for spiritual gifts, let it be for the edification of the church that you seek to excel. Therefore let him who speaks in a tongue pray that he may interpret. For if I pray in a tongue, my spirit prays, but my understanding is unfruitful. What is the conclusion then? I will pray with the spirit, and I will also pray with the understanding. I will sing with the spirit, and I will also sing with the understanding. Otherwise, if you bless with the spirit, how will he who occupies the place of the uninformed say “Amen” at your giving of thanks, since he does not understand what you say? For you indeed give thanks well, but the other is not edified. I thank my God I speak with tongues more than you all;
