1 Corinthians 14:1-4

Follow after love; yet desire earnestly spiritual gifts, but rather that ye may prophesy. For he that speaketh in a tongue speaketh not unto men, but unto God; for no man understandeth; but in the spirit he speaketh mysteries. But he that prophesieth speaketh unto men edification, and exhortation, and consolation. He that speaketh in a tongue edifieth himself; but he that prophesieth edifieth the church.
