1 Thessalonians 5:20

“Despise not prophesyings.] Or “prophecies”; the prophecies of the Old Testament concerning the first coming of Christ, concerning his person, office, and work, his obedience, sufferings, and death, his resurrection from the dead, ascension and session at God's right hand; for though all these are fulfilled, yet they have still their usefulness; for by comparing these with facts, the perfections of God, his omniscience, truth, faithfulness, wisdom, etc. are demonstrated, the authority of the Scriptures established, the truths of the Gospel illustrated and confirmed, and faith strengthened; and besides, there are many prophecies which regard things to be done, and yet to be done under the…”

“prophesyings--whether exercised in inspired teaching, or in predicting the future. "Despised" by some as beneath "tongues," which seemed most miraculous; therefore declared by Paul to be a greater gift than tongues, though the latter were more showy (Co1 14:5).”

“Despise not prophesyings - On the subject of prophesyings in the early Christian church, see the notes on 1 Corinthians 14:1 ff1 ff. The reference here seems to be to preaching. They were not to undervalue it in comparison with other things. It is possible that in Thessalonica, as appears to have been the case subsequently in Corinth (compare 1 Corinthians 14:19), there were those who regarded the power of working miracles, or of speaking in unknown tongues, as a much more eminent endowment than that of stating the truths of religion in language easily understood. It would not be unnatural that comparisons should be made between these two classes of endowments, much to the disadvantage of…”

“Despise not prophesyings - That is, preaching; for the apostle is not here speaking of extraordinary gifts. It seems, one means of grace is put for all; and whoever despises any of these, under whatever pretence, will surely (though perhaps gradually and almost insensibly) quench the Spirit. 1 Thessalonians 5:21”

“5:20-21 Prophecy, meant to build up the church (1 Cor 14:1-4), should not be rejected. Instead, the Thessalonians should test the prophecies (1 Cor 12:10; 14:29) to discern their origin, to check their agreement with the teaching of the apostles (2 Thes 2:2; 1 Jn 4:1-3), and to gauge the character of those who utter them (Matt 7:15-20). Early Christian teaching said, “Not everyone who speaks about spiritual things is a prophet, but only if the person’s conduct is like the Lord” (Didache 11:8). They should hold on to what is good—namely, prophecies that have been tested and found to be genuine.”
