1 Corinthians 14:4

4 He that speaketh in an unknown tongue edifieth himself; but he that prophesieth edifieth the church.

1 Corinthians 14:4 In-Context

2 For he that speaketh in an unknown tongue speaketh not unto men, but unto God: for no man understandeth him; howbeit in the spirit he speaketh mysteries.
3 But he that prophesieth speaketh unto men to edification, and exhortation, and comfort.
4 He that speaketh in an unknown tongue edifieth himself; but he that prophesieth edifieth the church.
5 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 interpret, that the church may receive edifying.
6 Now, brethren, if I come unto you speaking with tongues, what shall I profit you, except I shall speak to you either by revelation, or by knowledge, or by prophesying, or by doctrine?
