²⁰ Brethren, do not be children in your thinking; be babes in evil, but in thinking be mature. ²¹ In the law it is written, “By men of strange tongues and by the lips of foreigners will I speak to this people, and even then they will not listen to me, says the Lord.” ²² Thus, tongues are a sign not for believers but for unbelievers, while prophecy is not for unbelievers but for believers. ²³ If, therefore, the whole church assembles and all speak in tongues, and outsiders or unbelievers enter, will they not say that you are mad? ²⁴ But if all prophesy, and an unbeliever or outsider enters, he is convicted by all, he is called to account by all, ²⁵ the secrets of his heart are disclosed; and so, falling on his face, he will worship God and declare that God is really among you.

Orderly Worship

²⁶ What then, brethren? When you come together, each one has a hymn, a lesson, a revelation, a tongue, or an interpretation. Let all things be done for edification. ²⁷ If any speak in a tongue, let there be only two or at most three, and each in turn; and let one interpret. ²⁸ But if there is no one to interpret, let each of them keep silence in church and speak to himself and to God. ²⁹ Let two or three prophets speak, and let the others weigh what is said. ³⁰ If a revelation is made to another sitting by, let the first be silent. ³¹ For you can all prophesy one by one, so that all may learn and all be encouraged; ³² and the spirits of prophets are subject to prophets. ³³ For God is not a God of confusion but of peace.

As in all the churches of the saints,

³⁹ So, my brethren, earnestly desire to prophesy, and do not forbid speaking in tongues; ⁴⁰ but all things should be done decently and in order.
