HERE IT IS!
2 And it shall come to pass in the a last days, that the b mountain of the Lord ’s c house shall be d established in the top of the mountains, and shall be exalted above the hills; and all e nations shall flow unto it.
3 And many people shall go and say, Come ye, and let us a go up to the b mountain of the Lord , to the c house of the God of Jacob; and he will d teach us of his ways, and we will walk in his paths: for out of e Zion shall go forth the f law, and the word of the Lord from Jerusalem.
The “mountain of the Lord” refers to the temple. In Isaiah 2:2–4, Isaiah reported a vision and made a prophecy that has been fulfilled in many ways. He said that when the time comes that the Lord’s people put Him and His house above all things, and when they actively seek counsel from Him by going to His house, then Zion will be established among them and they will have peace and the promise of eternal life. Modern prophets have taught us the same doctrine. President Howard W. Hunter said, “Let us make the temple, with temple worship and temple covenants and temple marriage, our ultimate earthly goal and the supreme mortal experience” (in Conference Report, Oct. 1994, 118; or Ensign, Nov. 1994, 88 ).
Another fulfillment of this prophecy has to do with the Lord’s house being established in the “top of the mountains” (Isaiah 2:2). Not only does the prophecy have symbolic reference to putting the temple in the highest place in our lives, but it also has a literal fulfillment in the location of the Church headquarters in the latter days. Regarding this prophecy of Isaiah, Elder Bruce R. McConkie said, “This has specific reference to the Salt Lake Temple and to the other temples built in the top of the Rocky Mountains, and it has a general reference to the temple yet to be built in the New Jerusalem in Jackson County, Missouri” (A New Witness for the Articles of Faith [1985], 539).
Elder B. H. Roberts taught the importance of the law going forth from Zion when he said, “To me that is, in part, the law of Zion—the basic principle of the civil law of the land—a principle of the law that is going forth from Zion—the civil law that is to be established and maintained upon this blessed land of liberty, and that, eventually, will directly or indirectly bless and make free every land in all the world” (in Conference Report, Apr. 1908, 108). .
