James 2:25-26

Likewise also, &c. After Abraham, the father of the Jews, the apostle cites Rahab, a woman and a sinner of the Gentiles, to show that in every nation and sex true faith produces works, and is perfected by them; that is, by the grace of God working in the believer, while he is showing his faith by his works: see note on Hebrews 11:31. “Rahab's faith consisted in her attending to, and reasoning justly on, what she had heard concerning the dividing of the waters of the Red sea for a passage to the Israelites, and concerning the destruction of Sihon and Og. For from these things she concluded that the God of the Israelites was the true God, and sole Governor of the universe; and, firmly believing this, she renounced her former false gods, and concealed the Israelitish spies at the hazard of her life. In this she showed a disposition of the same kind with that which Abraham showed, when he left his country and kindred at God's command. And as Abraham, for that great act of faith and obedience, was rewarded with the promise of Canaan, so Rahab, as the reward of her faith and works, was not destroyed with the unbelieving inhabitants of Jericho.” For as the body without the spirit is dead Has no sense or feeling, no vital heat, action, or energy, but is a mere carcass, how fair and entire soever it may appear, and will at length fall into putrefaction and dissolution; so such a faith as is without works is dead also Now appears as a carcass in the sight of God, is useless, yea, loathsome and offensive. Two things, then, of great importance must be attended to on this subject. 1st, That the best outward works without faith are dead; they want their root and vital principle; for it is only by faith that any thing which we do is really good, as being done with an eye to the glory of God, and in obedience to him. 2d, That the most plausible profession of faith without works is dead, as the root is dead when it does not vegetate, when it produces no fruit. Faith is the root, good works are the fruits, and we must see to it that we have both. We must not think that either of them, without the other, will justify and save us. This is the grace of God wherein we stand, and we must take care that we stand in it.
