'They shall feed in the ways, and their pastures shall be in all high places.' ISAIAH xlix. 9. This is part of the prophet's glowing description of the return of the Captives, under the figure of a flock fed by a strong shepherd. We have often seen, I suppose, a flock of sheep driven along a road, some of them hastily trying to snatch a mouthful from the dusty grass by the wayside. Little can they get there; they have to wait until they reach some green pasture in which they can be folded. This flock shall 'feed in the ways'; as they go they will find nourishment. That is not all; the top of the mountains is not the place where grass grows. _There_ are bare, savage cliffs, from which every particle of soil has been washed by furious torrents, or the scanty vegetation has been burnt up by the fierce 'sunbeams like swords.' There the wild deer and the ravens live, the sheep feed down in the valleys. But '_their_ pasture shall be in all high places.' The literal rendering is even more emphatic: 'Their pasture shall be in all _bare heights_,' where a sudden verdure springs to feed them according to their need. Whilst, then, this prophecy is originally intended simply to suggest the abundant supplies that were to be provided for the band of exiles as they came back from Babylon, there lie in it great and blessed principles which belong to the Christian pilgrimage, and the flock that follows Christ. They who follow Him, says my text, to begin with, shall find in the dusty paths of common life, and in all the smallnesses and distractions of daily duty, nourishment for their spirits. Do you remember what Jesus said? 'My meat is to do the will of Him that sent Me, and to finish His work.' We, too, may have the same meat to eat which the world knows not of, and He will give that hidden manna to the combatant as well as 'to him that overcometh.' In the measure in which 'we follow the Lamb whithersoever He goeth,' in that measure do we find--like the stores of provisions that Arctic explorers come upon, _cached_ for them--food in the wilderness, and nourishment for our highest life in our common work. That is a great promise, and it is a great duty.
