We can fancy what it is to be lost in a forest where a traveller may ride round in a circle, thinking he is advancing, till he dies. But it is as easy to be lost in a wilderness, where there is nothing to see, as in a wood where one can see nothing. And there is something even more ghastly in being lost below the broad heavens in the open face of day than 'in the close covert of innumerous boughs.' The monotonous swells of the sand-heaps, the weary expanse stretching right away to the horizon, no land-marks but the bleaching bones of former victims, the gigantic sameness, the useless light streaming down, and in the centre one tiny, black speck toiling vainly, rushing madly hither and thither--a lost man--till he desperately flings himself down and lets death bury him, that is the one picture suggested by the text. The other is of that same wilderness, but across it a mighty king has flung up a broad, lofty embankment, a highway raised above the sands, cutting across them so conspicuously that even an idiot could not help seeing it, so high above the land around that the lion's spring falls far beneath it, and the supple tiger skulks baffled at its base. It is like one of those roads which the terrible energy of conquering Rome carried straight as an arrow from the milestone in the Forum over mountains, across rivers and deserts, morasses and forests, to flash along them the lightning of her legions, and over whose solid blocks we travel to-day in many a land. The prophet has seen in his vision the blind and deaf cured, the capacities of human nature destroyed by sin restored. He has told us that this miraculous change has come from the opening of a spring of new life in the midst of man's thirsty desert, and now he gets before us, in yet another image, another aspect of the glorious change which is to follow that coming of the Lord to save, which filled the farthest horizon of his vision. The desert shall have a plain path on which those diseased men who have been healed journey. Life shall no longer be trackless, but God will, by His coming, prepare paths that we should walk in them; and as He has given the lame man power to walk, so will he also provide the way by which His happy pilgrims will journey to their home. I. The pathless wandering of godless lives.
