So then, one who speaks in a tongue should pray that he may interpret.

The one who speaks in a tongue builds himself up, ¹  but the one who prophesies builds up the church.

For the one speaking in a tongue does not speak to people but to God, for no one understands; he is speaking mysteries by the Spirit. ¹ 

If then I do not know the meaning of a language, I will be a foreigner to the speaker and the speaker a foreigner to me.

So I want you to understand that no one speaking by the Spirit of God says, “Jesus is cursed,” and no one can say, “Jesus is Lord,” except by the Holy Spirit.

I wish you all spoke in tongues, but even more that you would prophesy. The one who prophesies is greater than the one who speaks in tongues, unless he interprets so that the church may be strengthened.

Now, brothers and sisters, ¹  if I come to you speaking in tongues, how will I help you unless I speak to you with a revelation or with knowledge or prophecy or teaching?
