“Faithful is he that calleth you, etc.]” Into the fellowship of his Son, and to his kingdom and glory, and who continues to do so, not only externally by his word, but internally by his Spirit and grace. “Who also will do it.” Two things the apostle mentions as the ground of confidence that the above petition, would be heard and answered; that is, that God would wholly sanctify them, and preserve the whole of them blameless to the coming of Christ; and they are the faithfulness of God, and the effectual calling of his saints. God is faithful to his word, his covenant and promises; he has promised to sanctify and cleanse his people from all their sins, and to preserve them safe to…

“And the very God of peace, etc.]” Or “the God of peace himself”. The apostle follows his exhortations with prayer to God, knowing the weakness and impotency of the saints to receive them, and act according to them, and his own insufficiency to impress their minds with them; and that unless the Lord opened their ears to discipline, and sealed instruction to them, they would be useless and in vain: wherefore he applies to the throne of grace, and addresses God as “the God of peace”; so called, because of the concern he has in peace and reconciliation made by the blood of Christ, and because he is the giver of peace of conscience, and the author of peace, concord, and unity among the saints,…

“Abstain from all appearance of evil.]” Of doctrinal evil. Not only open error and heresy are to be avoided, but what has any show of it, or looks like it, or carries in it a suspicion of it, or may be an occasion thereof, or lead unto it; wherefore all new words and phrases of this kind should be shunned, and the form of sound words held fast; and so of all practical evil, not only from sin itself, and all sorts of sin, lesser or greater, as the Jews have a saying, “take care of a light as of a heavy commandment,” that is, take care of committing a lesser, as a greater sin, and from the first motions of sin; but from every…

“Prove all things, etc.]” That are said by the prophets, all the doctrines which they deliver; hear them, though they have not the gift of tongues, and all desirable advantages; do not reject them on that account, and refuse to hear them, for so, many useful men may be laid aside, and the Spirit of God in them be quenched; try their gifts, and attend to their doctrines, yet do not implicitly believe everything they say, but examine them according to the word of God the test and standard of truth; search the Scriptures, whether the things they say are true or not. Not openly erroneous persons, and known heretics, are to be heard and attended on, but the ministers of the word, or such…

“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 Gospel dispensation, and therefore should not be set at nought, but highly valued and esteemed: also the predictions of…

“Quench not the spirit.]” By which is meant, not the person of the Spirit, but either the graces of the spirit, which may be compared to light, and fire, and heat, to which the allusion is in the text; such as faith, which is a light in the soul, a seeing of the Son, and an evidence of things not seen; and love, which gives a vehement flame, which many waters cannot quench; and zeal, which is the boiling up of love, the fervency of it; and spiritual knowledge, which is also light, and of an increasing nature, and are all graces of the spirit: and though these cannot be totally extinguished, and utterly put out and lost, yet they may be greatly damped; the…
