Thematic Bible: Those that speak in an unknown tongue

Labour after charity, and be desirous of spiritual gifts: but especially that ye may prophesy. For he, that speaketh in an unknown tongue, speaketh not to men, but to God: for no one understandeth, though in spirit he speaketh mysteries. But he, that prophesieth, speaketh edification, and exhortation, and comfort to men. read more.
He, that speaketh in an unknown tongue, edifieth himself: but he, that prophesieth, edifieth the church. I could wish 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 interpret, that the church may receive edification.
