James 2:19

any true believer. to any such boasting hypocrite. thou pretendest to have faith, or admit thou hast faith; and an historical faith he might have, as Jas 2:19. I do not boast of my faith; or, to say nothing of my faith, yet works I do profess to have. there are two readings of these words, but in both the sense agrees with the rest of the apostle’s discourse. If we take the marginal reading, show me thy faith by thy works, the sense is, evidence the faith thou pretendest to by thy works, as the fruits of it; let thy actions vouch for thy profession. But if we take the reading in the text, without thy works, it is a kind of ironical expression; q.d. Make it appear by convincing arguments that thou hast true faith, when yet thou wantest works, the only argument of the truth of it. Understand here, but this thou canst not. I will easily prove my faith to be true and genuine, by those good works it brings forth in me. Demonstrate the cause to me without the effect, if thou canst; but I will easily demonstrate the cause by the effect, and prove the root of faith to be in me, by my bringing forth that fruit which is proper to it. It cannot hence be inferred, that wherever such works are, as men count and call good, there must needs be faith: the apostle’s meaning only is, that wherever true faith is, there good works will certainly be.

The devils also believe, and tremble. St. James compares indeed faith without other virtues and good works, to the faith of devils: but comparisons must never be stretched farther than they are intended. The meaning is, that such a faith in sinners is unprofitable to salvation, like that of devils, which is no more than a conviction from their knowledge of God; but faith which remains in sinners, is from a supernatural knowledge, together with a pious motion in their free will. (Witham)

4. We are taught to look upon a faith of bare speculation and knowledge as the faith of devils: Thou believest that there is one God; thou doest well; the devils also believe, and tremble, v. 19. That instance of faith which the apostle here chooses to mention is the first principle of all religion. "Thou believest that there is a God, against the atheists; and that there is but one God, against the idolaters; thou doest well: so far all is right. But to rest here, and take up a good opinion of thyself, or of thy state towards God, merely on account of thy believing in him, this will render thee miserable: The devils also believe, and tremble. If thou contentest thyself with a bare assent to articles of faith, and some speculations upon them, thus far the devils go. And as their faith and knowledge only serve to excite horror, so in a little time will thine." The word tremble is commonly looked upon as denoting a good effect of faith; but here it may rather be taken as a bad effect, when applied to the faith of devils. They tremble, not out of reverence, but hatred and opposition to that one God on whom they believe. To rehearse that article of our creed, therefore, I believe in God the Father Almighty, will not distinguish us from devils at last, unless we now give up ourselves to God as the gospel directs, and love him, and delight ourselves in him, and serve him, which the devils do not, cannot do.

Verses 14-26 Those are wrong who put a mere notional belief of the gospel for the whole of evangelical religion, as many now do. No doubt, true faith alone, whereby men have part in Christ's righteousness, atonement, and grace, saves their souls; but it produces holy fruits, and is shown to be real by its effect on their works; while mere assent to any form of doctrine, or mere historical belief of any facts, wholly differs from this saving faith. A bare profession may gain the good opinion of pious people; and it may procure, in some cases, worldly good things; but what profit will it be, for any to gain the whole world, and to lose their souls? Can this faith save him? All things should be accounted profitable or unprofitable to us, as they tend to forward or hinder the salvation of our souls. This place of Scripture plainly shows that an opinion, or assent to the gospel, without works, is not faith. There is no way to show we really believe in Christ, but by being diligent in good works, from gospel motives, and for gospel purposes. Men may boast to others, and be conceited of that which they really have not. There is not only to be assent in faith, but consent; not only an assent to the truth of the word, but a consent to take Christ. True believing is not an act of the understanding only, but a work of the whole heart. That a justifying faith cannot be without works, is shown from two examples, Abraham and Rahab. Abraham believed God, and it was reckoned unto him for righteousness. Faith, producing such works, advanced him to peculiar favours. We see then, ver. ( 24 ) , how that by works a man is justified, not by a bare opinion or profession, or believing without obeying; but by having such faith as produces good works. And to have to deny his own reason,…
