1 Corinthians 14:21-25

New International Version

²¹ In the Law^(A) it is written:

²² Tongues, then, are a sign, not for believers but for unbelievers; prophecy,^(C) however, is not for unbelievers but for believers. 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?^{(D) 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^(E) of their hearts are laid bare. So they will fall down and worship God, exclaiming, “God is really among you!”^(F)
