II. What the comfort is that belongs to God's people. 1. That the gospel of Christ shall be preached and published to the world: A law shall proceed from me, an evangelical law, the law of Christ, the law of faith, ch. ii. 3. This law is his judgment; for it is that law of liberty by which the world shall be governed and judged. This shall not only go forth, but shall continue and rest, it shall take firm footing and deep root in the world. It shall rest, not only for the benefit of the Jews, who had the first notice of it, but for a light of the people of other nations. It is this law, this judgment, that we are required to hearken and give ear to, at our peril; for how shall we escape if we neglect it and turn a deaf ear to it? When a law proceeds from God, he that has ears to hear, let him hear. 2. That this law and judgment shall bring with them righteousness and salvation, shall open a ready way to the children of men, that they may be justified and saved, v. 5. These are called God's righteousness and his salvation, because of his contriving and bringing them about. The former is a righteousness which he will accept for us and accept us for, and a righteousness which he will work in us and graciously accept of. The latter is the salvation of the Lord, for it arises from him and terminates in him. Observe, There is no salvation without righteousness; and, wherever there is the righteousness of God, there shall be his salvation. All those, and those only, that are justified and sanctified shall be glorified. 3. That this righteousness and salvation shall very shortly appear: My righteousness is near. It is near in time; behold, all things are now ready. It is near in place, not far to seek, but the word is nigh us, and Christ in the word, righteousness in the word, Rom. x. 8. My salvation has gone forth. The decree has gone forth concerning it; it shall as certainly be introduced as if it had gone forth already, and the time for it is at hand. 4. That this evangelical righteousness and salvation shall not be confined to the Jewish nation, but shall be extended to the Gentiles; My arms shall judge the people. Those that will not yield to the judgments of God's mouth shall be crushed by the judgments of his hand. Some shall thus be judged by the gospel, for for judgment Christ came into this world; but others, and those of the isles, shall wait upon him, and bid his gospel, and the commands as well as the comforts of it, welcome. It was a comfort to God's people, to his nation, that multitudes should be added to them, and the increase of their number should be the increase of their strength and beauty. It is added, And on my arm shall they trust, that arm of the Lord which is revealed in Christ, ch. liii. 1. Observe, God's arm shall judge the people that are impenitent, and yet on his arm shall others trust and be saved by it; for it is to us as we make it, a savour of life or of death. 5. That this righteousness and salvation shall be for ever, and shall never be abolished, v. 8. It is an everlasting righteousness that the Messiah brings in (Dan. ix. 24), an eternal redemption that he is the author of, Heb. v. 9. As it shall spread through all the nations of the earth, so it shall last through all the ages of the world. We must never expect any other way of salvation, any other covenant of peace or rule of righteousness, than what we have in the gospel, and what we have there shall continue to the end, Mt. xxviii. 20. It is for ever; for the consequences of it shall be to eternity, and by this law of liberty men's everlasting state will be determined. This perpetuity of the gospel and the blessed things it brings in is illustrated by the fading and perishing of this world and all things in it. Look up to the visible heavens above, which have continued hitherto, and seem likely to continue, but they shall vanish like smoke that soon spends itself and disappears; they shall be rolled like a scroll, and their lights shall fall like leaves in autumn. Look down to the earth beneath; that abides too for a short ever (Eccl. i. 4), but it shall wax old like a garment that will be the worse for wearing; and those that dwell therein, all the inhabitants of the earth, even those that seem to have the best settlement in it, shall die in like manner: the soul shall, as to this world, vanish like smoke, and the body be thrown by like a garment waxen old. They shall be easily crushed (Job iv. 19), and no loss of them. But when heaven and earth pass away, when all flesh and the glory of it wither as grass, the word of the Lord endures for ever, and not one iota or tittle of that shall fall to the ground. Those whose happiness is bound up in Christ's righteousness and salvation will have the comfort of it when time and days shall be no more.
