ACV(i)
20 Brothers, become not children in your thoughts. Instead be childlike in wickedness, but in your thoughts become mature.
21 In the law it is written, In other tongues and in other lips I will speak to this people, and not even so will they hear me, says the Lord.
22 Therefore tongues are for a sign, not to those who believe, but to the unbelieving. But prophesying is not to the unbelieving, but to those who believe.
23 If therefore the whole congregation comes together in the same place, and all speak in tongues, and unlearned or unbelieving men come in, will they not say that ye are mad?
24 But if all prophesy, and some unbelieving or unlearned man comes in, he is convicted by all, he is called to account by all.
25 And so the secrets of his heart are made manifest. And so having fallen down on his face he will worship God, declaring that God is really among you.
