NSB(i)
19 Yet in the congregation I would rather speak five words with my understanding than ten thousand words in an unknown tongue.
20 Brothers, do not be like children in understanding. When it comes to evil be innocent children but in your thinking be mature adults.
21 It is written in the law: »With men of other tongues and lips of foreigners I will speak to this people. Even then they will not listen to me,« said Jehovah.
22 Therefore speaking in tongues is a sign not for believers, but for those who do not believe. Prophesying (proclaiming God’s Word) serves the believer and not the unbeliever.
23 If therefore the whole congregation comes together in one place, and all speak with tongues, and the unlearned, or unbelievers, come there will they not say that you are out of your mind?
24 But if all proclaim God’s Word and an unbeliever comes there he is convinced by all.
25 The secrets of his heart are made known. So falling down on his face he will worship God, and report, »God is truly among you.«
