1 Corinthians 14:23-25

New King James Version

²³ Therefore if the whole church comes together in one place, and all speak with tongues, and there come in those who are uninformed or unbelievers, ^(A)will they not say that you are ^[a]out of your mind? ²⁴ But if all prophesy, and an unbeliever or an uninformed person comes in, he is convinced by all, he is convicted by all. ^25 [b]And thus the secrets of his heart are revealed; and so, falling down on his face, he will worship God and report ^(B)that God is truly among you.
