1 Corinthians 14:2-4

New Century Version

² I will explain why. Those who have the gift of speaking in different languages^[a] are not speaking to people; they are speaking to God. No one understands them; they are speaking secret things through the Spirit. ³ But those who prophesy are speaking to people to give them strength, encouragement, and comfort. ⁴ The ones who speak in different languages are helping only themselves, but those who prophesy are helping the whole church.
