'In this mountain shall the Lord of hosts make unto all people a feast of fat things, a feast of wines on the lees, of fat things full of marrow, of wines on the lees well refined. 7. And He will destroy in this mountain the face of the covering cast over all people, and the veil that is spread over all nations. 8. He will swallow up death in victory.'--ISAIAH xxv. 6-8. A poet's imagination and a prophet's clear vision of the goal to which God will lead humanity are both at their highest in this great song of the future, whose winged words make music even in a translation. No doubt it starts from the comparatively small fact of the restoration of the exiled nation to its own land. But it soars far beyond that. It sees all mankind associated with them in sharing their blessings. It is the vision of God's ideal for humanity. That makes it the more remarkable that the prophet, with this wide outlook, should insist with such emphasis on the fact that it has a local centre. That phrase 'in this mountain' is three times repeated in the hymn; two of the instances occurring in the verses of my text have lying side by side with them the expressions 'all people' and 'all nations,' as if to bring together the local origin, and the universal extent, of the blessings promised. The sweet waters that are to pour through the world well up from a spring opened 'in this mountain.' The beams that are to lighten every land stream out from a light blazing there. The world's hopes for that golden age which poets have sung, and towards which earnest social reformers have worked, and of the coming of which this prophet was sure, rest on a definite fact, done in a definite place, at a definite time. Isaiah knew the place, but what was to be done, or when it was to be done, he knew not. You and I ought to be wiser. History has taught us that Jesus Christ fulfils the visioned good that inspired the prophet's brilliant words. We might say, with allowable licence, that 'this mountain,' in which the Lord does the great things that this song magnifies, is not so much Zion as Calvary. Brethren, in these days, when so many voices are proclaiming so many short cuts to the Millennium, this clear declaration of the source of the world's hope is worth pondering. For us all, individually, this localisation of the origin of the universal good of mankind is an offer of blessings to us if we will go thither, where the provision for the world's good is stored--'In this mountain'; therefore, to seek it anywhere else is to seek it in vain. Now, I wish, under the impression of that conviction, to put before you just these three thoughts: where the world's food comes from; where the unveiling which gives light to the world comes from; and where the life which destroys death for the world comes from--'In this mountain.' I. Where does the world's food come from?
