James: Practical faith
James 2
The Law of Liberty
Dead Faith
Faith that yields no deeds is not saving faith. The NT does not teach justification by works, but it also does not teach justification by the profession of faith or the claim to faith; it teaches justification by the possession of true faith, and true faith always bears the fruit of love of God and neighbor. James has in mind a genuine, living faith that produces fruitful works, which is evidence that will vindicate (or prove) the validity of one’s authentic justifying faith at the last judgment.
Paul means by it the gratuitous imputation of righteousness before the tribunal of God; and James, the manifestation of righteousness by the conduct, and that before men, as we may gather from the preceding words, “Shew to me thy faith,” &c. In this sense we fully allow that man is justified by works, as when any one says that a man is enriched by the purchase of a large and valuable estate, because his riches, before hid, shut up in a chest, were thus made known.
