One road, and the Way it points to
The Highway of Holiness
Deserts have their own roads. Caravans and pilgrims once crossed the wilderness on tracks worn smooth by countless feet, but those roads were open to anyone, and they were dangerous. Bandits waited at the fords. Wild animals prowled the ravines. To travel was to gamble. When Isaiah 35 imagines the desert coming back to life, blossoming and flooding with water, it does not stop at scenery. It lays down a road. And this road is unlike any other, because of who is permitted to walk it and who is not. The promise in Isaiah 35 is that a highway will run through the transformed wilderness, and it will be called the Way of Holiness. It is a strange combination of images: an engineered road, a public thoroughfare, named for something as inward as holiness. This piece follows that road, asking what it means for God to build not only a destination but the very way to reach it, and to reserve that way for a people He has ransomed.
“And an highway shall be there, and a way, and it shall be called The way of holiness; the unclean shall not pass over it; but it shall be for those: the wayfaring men, though fools, shall not err therein.”Isaiah 35:8
The way in Scripture
Isaiah 35 stands as a bright chapter set between darker ones. The chapters before it thunder with judgment against the nations, and the chapters after it turn to the crisis of Hezekiah and the looming Assyrian threat. Into that pressure Isaiah drops a vision of reversal. The desert rejoices, the wilderness blossoms, the weak hands are strengthened, the blind see, the deaf hear, the lame leap. It is a portrait of creation itself being healed, and at the center of the healing lies a road. The road is described with unusual precision in Isaiah 35:8. It is a highway, a raised and prepared way, the kind of engineered path that took labor to build. It bears a name, the Way of Holiness. And then Isaiah adds the striking qualification: the unclean will not pass over it. This is not a road defined only by its surface or its direction, but by the moral condition of those who use it. It is the redeemed who walk there. Isaiah continues in verses 9 and 10 by describing what will not be found on this road. No lion, no ravenous beast, nothing to threaten the traveler. The dangers that made every ancient journey a risk are simply absent. The road is safe not because the wilderness has been fenced, but because the threats have been removed. And along this cleared and guarded way come the ransomed of the Lord, returning to Zion with singing, with everlasting joy upon their heads, while sorrow and sighing flee. Read in its own context, the chapter almost certainly speaks first to exiles, to a scattered people who will one day come home. The road is their homeward road, a way through the wilderness that separates captivity from Zion. Yet Isaiah gives the road a name too large for a single homecoming. To call a highway the Way of Holiness is to say that the journey home and the journey into God's own character are somehow the same journey.
What it comes to mean
The first thing to notice is that this is a built road. Highways in the ancient world were not accidents of foot traffic; they were raised, cleared, and maintained, often for kings and armies. When Isaiah names God as the one who provides this way, he is claiming that the return of a broken people is not a lucky escape but a prepared work. Someone went ahead. Someone did the labor of making a road where the terrain offered none. The second thing is the strange fusion of the public and the pure. A highway is the most public thing imaginable, open by definition. Holiness, in the Hebrew imagination, is the most set-apart thing imaginable, guarded and restricted. Isaiah welds them together. The Way of Holiness is a public road that only the clean may travel. This is not snobbery; it is honesty about what holiness is. To walk with God is to walk on ground where uncleanness cannot survive, not because travelers are turned away at a gate, but because the road itself does something to those on it. Here we must be careful and honest. The verse says the unclean will not pass over it, and taken alone that could sound like exclusion, a road for the already-good. But the chapter undercuts that reading. The travelers are named the ransomed and the redeemed. These are not words for the self-sufficient. To be ransomed is to have been in a position you could not buy your way out of. The people on this road are not clean because they qualified; they are clean because they were redeemed. The road is holy, and it makes its travelers what they could not make themselves. Isaiah even adds a tender note in the same verse: the wayfaring, though fools, shall not err on this road. The way is so clearly marked, so surely guarded, that even the simple cannot lose it. This is worth sitting with. Many roads to virtue in the ancient and modern world are roads for the sophisticated, the disciplined, the elite. This road is deliberately built for people who would get lost anywhere else. Its safety is not in the traveler's competence but in the road's design. So the meaning gathers into a single claim: God does not merely command holiness from a distance and wait to see who arrives. He builds the way to it, clears the predators from it, marks it so plainly that fools stay on it, and reserves it for a people He has already paid to set free. Holiness, in Isaiah 35, is less a standard we scale than a road we are set upon.
How it points to Christ, the Way
The New Testament writers heard Isaiah 35 as more than a homecoming poem. When John the Baptist prepared people for one greater than himself, the language of a way made ready in the wilderness stood close at hand. And when Jesus was asked for proof of who He was, He pointed to exactly the signs Isaiah 35 had promised: the blind seeing, the deaf hearing, the lame walking. He was, in effect, saying that the chapter's healing had arrived, and if the healing had arrived, so had the road. The deepest link is the road's central problem. Isaiah says the unclean cannot walk the Way of Holiness, yet the travelers are called the ransomed. Someone had to pay the ransom that makes an unclean people fit for a holy road. The Gospels answer that question with a cross. The cleansing that Isaiah names but does not explain is accomplished when Christ takes the uncleanness of His people upon Himself, so that those who could not pass over the road are made able to walk it. And Jesus does not only clear the road; He is the road. He calls Himself the Way, and the earliest believers were simply called people of the Way. Isaiah's highway, named for holiness and reserved for the redeemed, finds its person in the one who is both holy and the redeemer. To walk the Way of Holiness is not, finally, to follow a set of directions. It is to follow Him.
Questions people ask
Does the Way of Holiness in Isaiah 35 exclude sinners?
It excludes uncleanness, yet its named travelers are the ransomed and the redeemed, words that assume people who could not free themselves. The road does not welcome the already-good; it cleanses those God has purchased. Exclusion of sin and inclusion of sinners hold together, because the road itself makes travelers fit.
Was Isaiah 35 about the return from exile or about something more?
In its setting it speaks first to a scattered people returning home through the wilderness to Zion. Yet naming the road the Way of Holiness gives it a reach beyond one homecoming, suggesting that the journey home and the journey into God's character are one, a hope the New Testament sees fulfilled in Christ.
