III. The way of religion and godliness shall be laid open: it is here called the way of holiness (v. 8) the way both of holy worship and a holy conversation. Holiness is the rectitude of the human nature and will, in conformity to the divine nature and will. The way of holiness is that course of religious duties in which men ought to walk and press forward, with an eye to the glory of God and their own felicity in the enjoyment of him. "When our God shall come to save us he shall chalk out to us this way by his gospel, so as it had never been before described." 1. It shall be an appointed way; not a way of sufferance, but a highway, a way into which we are directed by a divine authority and in which we are protected by a divine warrant. It is the King's highway, the King of Kings' highway, in which, though we may be waylaid, we cannot be stopped. The way of holiness is the way of God's commandments; it is (as highways usually are) the good old way, Jer. vi. 16. 2. It shall be an appropriated way, the way in which God will bring his own chosen to himself, but the unclean shall not pass over it, either to defile it or to disturb those that walk in it. It is a way by itself, distinguished from the way of the world, for it is a way of separation from, and nonconformity to, this world. It shall be for those whom the Lord has set apart for himself (Ps. iv. 3), shall be reserved for them: The redeemed shall walk there, and the satisfaction they take in these ways of pleasantness shall be out of the reach of molestation from an evil world. The unclean shall not pass over it, for it shall be a fair way; those that walk in it are the undefiled in the way, who escape the pollution that is in the world. 3. It shall be a straight way: The wayfaring men, who choose to travel in it, though fools, of weak capacity in other things, shall have such plain directions from the word and Spirit of God in this way that they shall not err therein; not that they shall be infallible even in their own conduct, or that they shall in nothing mistake, but they shall not be guilty of any fatal misconduct, shall not so miss their way but that they shall recover it again, and get well to their journey's end. Those that are in the narrow way, though some may fall into one path and others into another, not all equally right, but all meeting at last in the same end, shall yet never fall into the broad way again; the Spirit of truth shall lead them into all truth that is necessary for them. Note, The way to heaven is a plain way, and easy to hit. God has chosen the foolish things of the world, and made them wise to salvation. Knowledge is easy to him that understands. 4. It shall be a safe way: No lion shall be there, nor any ravenous beast (v. 9), none to hurt or destroy. Those that keep close to this way keep out of the reach of Satan the roaring lion, that wicked one touches them not. Those that walk in the way of holiness may proceed with a holy security and serenity of mind, knowing that nothing can do them any real hurt; they shall be quiet from the fear of evil. It was in Hezekiah's days, some time after the captivity of the ten tribes, that God, being displeased with the colonies settled there, sent lions among them, 2 Kings xvii. 25. But Judah keeps her integrity, and therefore no lions shall be there. Those that walk in the way of holiness must separate themselves from the unclean and the ravenous, must save themselves from an untoward generation; hoping that they themselves are of the redeemed, let them walk with the redeemed who shall walk there.
