1 Corinthians 14:16
16 Otherwise, if you give thanks with your spirit, how can anyone in the position of an outsider1 say f“Amen” to gyour thanksgiving when he does not know what you are saying?
1 Corinthians 14:23–25
23 If, therefore, the whole church comes together and all speak in tongues, and outsiders or unbelievers enter, mwill they not say that you are out of your minds? 24 But if all prophesy, and an unbeliever or outsider enters, he is convicted by all, he is called to account by all, 25 nthe secrets of his heart are disclosed, and so, ofalling on his face, he will worship God and pdeclare that God is really among you.
