Brothers, stop thinking like children.1 In regard to evil be infants,2 but in your thinking be adults.
In the Law3 it is written: "Through men of strange tongues and through the lips of foreigners I will speak to this people, but even then they will not listen to me,"a4 says the Lord.
Tongues, then, are a sign, not for believers but for unbelievers; prophecy,5 however, is for believers, not for unbelievers.
So if the whole church comes together and everyone speaks in tongues, and some who do not understandb or some unbelievers come in, will they not say that you are out of your mind?624
But if an unbeliever or someone who does not understandc comes in while everybody is prophesying, he will be convinced by all that he is a sinner and will be judged by all,
and the secrets7 of his heart will be laid bare. So he will fall down and worship God, exclaiming, "God is really among you!"8
What then shall we say, brothers?9 When you come together, everyone10 has a hymn,11 or a word of instruction,12 a revelation, a tongue13 or an interpretation.14 All of these must be done for the strengthening15 of the church.
If anyone speaks in a tongue, two--or at the most three--should speak, one at a time, and someone must interpret.
If there is no interpreter, the speaker should keep quiet in the church and speak to himself and God.
Two or three prophets16 should speak, and the others should weigh carefully what is said.1730
And if a revelation comes to someone who is sitting down, the first speaker should stop.
