20 Brothers, hdo not be children in your thinking. iBe infants in evil, but in your thinking be jmature. 21 kIn the Law it is written, l“By people 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 a sign3 not for unbelievers but for believers. 23 If, therefore, the whole church comes together and all speak in tongues, and outsiders or unbelievers enter, mwill they not say that you are out of your minds? 24 But if all prophesy, and an unbeliever or outsider enters, he is convicted by all, he is called to account by all, 25 nthe secrets of his heart are disclosed, and so, ofalling on his face, he will worship God and pdeclare that God is really among you.
