1 Corinthians 14:18-25

18I thank God, I speak in tongues more than you all; 19nevertheless, in church I prefer to speak five words with my mind so that I may instruct others also, rather than ten thousand words in a tongue.

201Brothers and sisters, 2do not be children in your thinking; yet in evil 3be infants, but in your thinking be mature. 21In 4the 5Law it is written: “6By men of strange tongues and by the lips of strangers I will speak to this people, and even so they will not listen to Me,” says the Lord. 22So then, tongues are for a sign, not to those who believe but to unbelievers; but 7prophecy is not for unbelievers, but for those who believe. 23Therefore if the whole church gathers together and all the people speak in tongues, and 8outsiders or unbelievers enter, will they not say that 9you are insane? 24But if all 10prophesy, and an unbeliever or an 11outsider enters, he is 12convicted by all, he is called to account by all; 2513the secrets of his heart are disclosed; and so he will 14fall on his face and worship God, 15declaring that God is certainly among you.
