1 Corinthians 14:23-25

New International Version

²³ So if the whole church comes together and everyone speaks in tongues, and inquirers or unbelievers come in, will they not say that you are out of your mind?^{(A) 24} But if an unbeliever or an inquirer comes in while everyone is prophesying, they are convicted of sin and are brought under judgment by all, ²⁵ as the secrets^(B) of their hearts are laid bare. So they will fall down and worship God, exclaiming, “God is really among you!”^(C)
