1 Corinthians 14:23-28

23Even so, if unbelievers or people who don’t understand these things come into your church meeting and hear everyone speaking in an unknown language, they will think you are crazy.

24But if all of you are prophesying, and unbelievers or people who don’t understand these things come into your meeting, they will be convicted of sin and judged by what you say.

25As they listen, their secret thoughts will be exposed, and they will fall to their knees and worship God, declaring, “God is truly here among you.”

26Well, my brothers and sisters, let’s summarize. When you meet together, one will sing, another will teach, another will tell some special revelation God has given, one will speak in tongues, and another will interpret what is said. But everything that is done must strengthen all of you.

27No more than two or three should speak in tongues. They must speak one at a time, and someone must interpret what they say.

28But if no one is present who can interpret, they must be silent in your church meeting and speak in tongues to God privately.
