1 Corinthians 14:6, 26

Dear brothers and sisters, if I should come to you speaking in an unknown language, how would that help you? But if I bring you a revelation or some special knowledge or prophecy or teaching, that will be helpful.

Well, my brothers and sisters, let’s summarize. When you meet together, one will sing, another will teach, another will tell some special revelation God has given, one will speak in tongues, and another will interpret what is said. But everything that is done must strengthen all of you.
