Thematic Bible: Those that speak in an unknown tongue

Labour for love, and covet spiritual gifts: and most chiefly for to prophesy. For he that speaketh with tongues speaketh not unto men, but unto God. For no man heareth him: Howbeit, in the spirit he speaketh mysteries. But he that prophesieth speaketh unto men, to edifying, to exhortation, and to comfort. read more.
He that speaketh with tongues, profiteth himself: he that prophesieth, edifieth the congregation. I would that ye all spake with tongues: but rather that ye prophesied. For greater is he that prophesieth, than he that speaketh with tongues, except he expound it also, that the congregation may have edifying.
