It can hardly be necessary to dwell at length on the commentary which we find in the Epistle of James on the faith of Rahab. For it is not so much anything personal to her that he handles, but an important quality of all true faith, and of her faith as being true. "Was not Rahab the harlot justified by works when she had received the messengers, and had sent them out another way?" No intelligent person needs to be told that the view of justification here given is in no wise at variance with that of St. Paul. Paul's doctrine was propounded in the early years of the Church, when, in opposition to the notion prevalent among the Gentiles, it was necessary to show clearly that there was no justifying merit in works. The doctrine of James was propounded at a later period, when men, presuming on free grace, were beginning to get lax in their practice, and it was necessary to insist that faith could not be true faith if it was not accompanied by corresponding works. The case of Rahab is employed by St. James to illustrate this latter position. If Rahab had merely professed belief in the God of Israel as the only true God, and in the certainty that Israel would possess the land, according to God's promise, her faith would have been a barren or dead faith; in other words, it would have been no true faith at all. It was her taking up the cause of the spies, protecting them, endangering her life for them, and then devising and executing a scheme for their safety, that showed her faith to be living, and therefore real. Let it be true that faith is only the instrument of justification, that it possesses no merit, and that its value lies solely in its uniting us to Christ, so that we get justification and all other blessings from Him; still that which really unites us to Christ must be living. Dr. Chalmers used to sum up the whole doctrine in the formula, "We are justified by faith alone, but not by a faith which is alone."
