2 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. 3 But he that prophesieth speaketh unto men edification, and exhortation, and consolation. 4 He that speaketh in a tongue edifieth himself; but he that prophesieth edifieth the church.
Matthew Henry's Commentary on 1 Corinthians 14:2-4
Commentary on 1 Corinthians 14:1-5
(Read 1 Corinthians 14:1-5)
Prophesying, that is, explaining Scripture, is compared with speaking with tongues. This drew attention, more than the plain interpretation of Scripture; it gratified pride more, but promoted the purposes of Christian charity less; it would not equally do good to the souls of men. What cannot be understood, never can edify. No advantage can be reaped from the most excellent discourses, if delivered in language such as the hearers cannot speak or understand. Every ability or possession is valuable in proportion to its usefulness. Even fervent, spiritual affection must be governed by the exercise of the understanding, else men will disgrace the truths they profess to promote.
