1 Corinthians 14:2-4

New Living Translation

² For if you have the ability to speak in tongues,^[a] you will be talking only to God, since people won’t be able to understand you. You will be speaking by the power of the Spirit,^[b] but it will all be mysterious. ³ But one who prophesies strengthens others, encourages them, and comforts them. ⁴ A person who speaks in tongues is strengthened personally, but one who speaks a word of prophecy strengthens the entire church.
