1 Corinthians 14:23-25

International Standard Version

²³ Now if the whole church gathers in the same place and everyone is speaking in foreign languages, when uneducated people or unbelievers come in, they will say that you are out of your mind, won’t they? ²⁴ But if everyone is prophesying, when an unbeliever or an uneducated person comes in he will be convicted and examined by everything that’s happening.^{[a] 25} His secret, inner heart will become known, and so he will bow down to the ground and worship God, declaring, “God is truly among you!”
