1 Corinthians 14:1-5 (NIV)

14 Follow the way of love and eagerly desire gifts of the Spirit, especially prophecy. 2 For anyone who speaks in a tongue does not speak to people but to God. Indeed, no one understands them; they utter mysteries by the Spirit. 3 But the one who prophesies speaks to people for their strengthening, encouraging and comfort. 4 Anyone who speaks in a tongue edifies themselves, but the one who prophesies edifies the church. 5 I would like every one of you to speak in tongues, but I would rather have you prophesy. The one who prophesies is greater than the one who speaks in tongues, unless someone interprets, so that the church may be edified.
