Yet in the church I had rather speak five words with my understanding, that by my voice I might teach others also, than ten thousand words in an unknown tongue.
He who speaks in an unknown tongue edifies himself, but he who prophesies edifies the church.
that you might know the certainty of the things which you have been told.
I thank my God that I speak in tongues more than you all.
Brothers, do not be children in your thinking; rather be infants in evil, but in your thinking be mature.
