21. In the law it is written: In other tongues and other lips I will speak to this people; and neither so will they hear me, saith the Lord.
22. Wherefore tongues are for a sign, not to believers, but to unbelievers; but prophecies not to unbelievers, but to believers.
23. If therefore the whole church come together into one place, and all speak with tongues, and there come in unlearned persons or infidels, will they not say that you are mad?
24. But if all prophesy, and there come in one that believeth not, or an unlearned person, he is convinced of all, he is judged of all.
25. The secrets of his heart are made manifest; and so, falling down on his face, he will adore God, affirming that God is among you indeed.
