20 Brothers, stop being children in intelligence, but as to evil keep on being babies; and yet as to intelligence be men of maturity.
21 In the law it is written, "By men of foreign languages and by the lips of foreigners I will speak to this people, but even then they will not listen to me, says the Lord."
22 So speaking in ecstasy is meant as a sign, not for believers but for unbelievers, while prophecy is meant, not for unbelievers but for believers.
23 Hence, if the whole church has met and everybody speaks in ecstasy, and illiterate people or unbelievers come in, will they not say that you are crazy?
24 But if everybody prophesies, and some unbeliever or illiterate man comes in, he is convinced of his sins by all, he is closely questioned by all,
25 the secrets of his heart are laid bare, he falls upon his face and worships God, declaring, "God is really among you."
