I Corinthians 14:1-5

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.
