By works was faith made perfect [1] By this he again shews, that the question here is not respecting the cause of our salvation, but whether works necessarily accompany faith; for in this sense it is said to have been perfected by works, because it was not idle. It is said to have been perfected by works, not because it received thence its own perfection, but because it was thus proved to be true. For the futile distinction which the Sophists draw from these words, between formed and unformed faith, needs no labored refutation; for the faith of Abram was formed and therefore perfected before he sacrificed his son. And this work was not as it were the finishing, or last work. Formerly things afterwards followed by which Abraham proved the increase of his faith. Hence this was not the perfection of his faith, nor did it then for the first time put on its form. James then understood no other thing, than that the integrity of his faith then appeared, because it brought forth that remarkable fruit of obedience.

1 - The previous sentence is hardly intelligible in our version or in Calvin's. "Seest thou how faith wrought (co-operated, by C.) with his works?" The verb is sunergeo, which means properly to work together, to co-operate; and it means also, as the effect of co-operating, to aid, to help. "Seest thou how faith aided him in his works?" Schleusner gives this paraphrase, "Thou sees that Abraham was aided by his faith to do his remarkable works." Beza's version is, "Thou seest that faith was the assistant (administer) of his works." Some give the idea of combining to co-operating, "Thou seest that faith co-operated with his works," that is, in justification. It has been said, that if this combination had been intended, it ought to have been said that works co-operated with his faith, as faith, according to the testimony of scripture and the nature of things, is the primary and the principal thing, and as there can be no good works without faith. But the first explanation is the most consonant with the words and with the drift of the passage.

Seest thou - Margin, "Thou seest." Either rendering is correct, and the sense is the same. The apostle means to say that this was so plain that they could not but see it.
How faith wrought with his works - συνήργει sunērgei. Cooperated with. The meaning of the word is, "to work together with anyone; to co operate," 1-Corinthians 16:16; 2-Corinthians 6:1; then to aid, or help, Mark 16:20; to contribute to the production of any result, where two or more persons or agents are united. Compare Romans 8:28. The idea here is, that the result in the case of Abraham, that is, his salvation, or his religion, was secured, not by one of these things alone, but that both contributed to it. The result which was reached, to wit, his acceptance with God, could not have been obtained by either one of them separately, but both, in some sense, entered into it. The apostle does not say that, in regard to the merit which justifies, they came in for an equal share, for he makes no affirmation on that point; he does not deny that in the sight of God, who foresees and knows all things, he was regarded as a justified man the moment he believed, but he looks at the result as it was, at Abraham as he appeared under the trial of his faith, and says that in that result there was to be seen the co-operation of faith and good works. Both contributed to the end, as they do now in all cases where there is true religion.
(By the somewhat unhappy term "merit," the author clearly means nothing more than "principle," as is obvious from his acute and evangelical comment on the verse; as well as from the admirable reconciliation of Paul and James below.)
And by works was faith made perfect - Made complete, finished, or entire. It was so carried out as to show its legitimate and fair results. This does not mean that the faith in itself was defective before this, and that the defect was remedied by good works; or that there is any deficiency in what the right kind of faith can do in the matter of justification, which is to be helped out by good works; but that there was that kind of completion which a thing has when it is fully developed, or is fairly carried out.

Seest thou how faith wrought - Here is a proof that faith cannot exist without being active in works of righteousness. His faith in God would have been of no avail to him, had it not been manifested by works; for by works - by his obedience to the commands of God, his faith was made perfect - it dictated obedience, he obeyed; and thus faith ετελειωθη, had its consummation. Even true faith will soon die, if its possessor do not live in the spirit of obedience.

Seest thou how faith (l) wrought with his works, and by works was faith made (m) perfect?
(l) Was effectual and fruitful with good works.
(m) That the faith was declared to be a true faith, through works.

Seest thou how faith wrought with his works,.... Not to justify him before God; for neither faith nor works are ever said in Scripture to justify any man; but his faith being of the right kind, a faith which works by love, it put him upon doing this work, and many others; for this was done in faith, Hebrews 11:17 as all good works are, which are properly such; and where there is true faith, it will influence and engage a man to do good works, as it did Abraham.
And by works was faith made perfect? not with an absolute perfection; for though Abraham's faith was very great, yet there were things lacking in it, and he had his fits and times of unbelief; and had he lived till now, his faith, in this sense, would not have been perfect; and he would have had reason to have used the apostle's petition, Luke 17:5 much less would it have been made thus perfect by works; but the sense is, that hereby his faith was declared to be sincere, unfeigned, true, and genuine; just as love is said to be perfected, 1-John 4:17.

Or, "thou seest."
how--rather, "that." In the two clauses which follow, emphasize "faith" in the former, and "works" in the latter, to see the sense [BENGEL].
faith wrought with his works--for it was by faith he offered his son. Literally, "was working (at the time) with his works."
by works was faith made perfect--not was vivified, but attained its fully consummated development, and is shown to be real. So "my strength is made perfect in weakness," that is, exerts itself most perfectly, shows how great it is [CAMERON]: so 1-John 4:17; Hebrews 2:10; Hebrews 5:9. The germ really, from the first, contains in it the full-grown tree, but its perfection is not attained till it is matured fully. So James 1:4, "Let patience have her perfect work," that is, have its full effect by showing the most perfect degree of endurance, "that ye may be perfect," that is, fully developed in the exhibition of the Christian character. ALFORD explains, "Received its realization, was entirely exemplified and filled up." So Paul, Philippians 2:12, "Work out your own salvation": the salvation was already in germ theirs in their free justification through faith. It needed to be worked out still to fully developed perfection in their life.

Thou seest that faith - For by faith Abraham offered him, Hebrews 11:17. Wrought together with his works - Therefore faith has one energy and operation; works, another: and the energy and operation of faith are before works, and together with them. Works do not give life to faith, but faith begets works, and then is perfected by them. And by works was faith made perfect - Here St. James fixes the sense wherein he uses the word justified; so that no shadow of contradiction remains between his assertion and St. Paul's. Abraham returned from that sacrifice perfected in faith, and far higher in the favour of God. Faith hath not its being from works, (for it is before them,) but its perfection. That vigour of faith which begets works is then excited and increased thereby, as the natural heat of the body begets motion, whereby itself is then excited and increased. See 1-John 3:22.
