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.
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.
He who speaks in an unknown tongue edifies himself, but he who prophesies edifies the church.
