1 Corinthians 14:23-25

Suppose the whole church meets together and everyone speaks in different languages. If some people come in who do not understand or do not believe, they will say you are crazy. But suppose everyone is prophesying and some people come in who do not believe or do not understand. If everyone is prophesying, their sin will be shown to them, and they will be judged by all that they hear. The secret things in their hearts will be made known. So they will bow down and worship God saying, “Truly, God is with you.”
