20Brothers, stop thinking like children. In regard to evil be infants, but in your thinking be mature.
21It is written in the Law: “By strange tongues and foreign lips I will speak to this people, but even then they will not listen to Me, says the Lord.”
22Tongues, then, are a sign, not for believers, but for unbelievers. Prophecy, however, is for believers, not for unbelievers.
23So if the whole church comes together and everyone speaks in tongues, and some who are uninstructed or some unbelievers come in, will they not say that you are out of your minds?
24But if an unbeliever or uninstructed person comes in while everyone is prophesying, he will be convicted and called to account by all,
25and the secrets of his heart will be made known. So he will fall facedown and worship God, proclaiming, “God is truly among you!”
