For example, we have the verse below from 2 Nephi 3, which doesn't refer to the others previously mentioned in the chapter.
Also, we have these two characters,2 Nephi 3: 24 And there shall rise up one mighty among them, who shall do much good, both in word and in deed, being an instrument in the hands of God, with exceeding faith, to work mighty wonders, and do that thing which is great in the sight of God, unto the bringing to pass much restoration unto the house of Israel, and unto the seed of thy brethren.
And we also have these verses.Revelation 11: 3 And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth.
I would guess from how things have turned out throughout history that we'll be surprised at how all this unfolds and whose been involved. I don't believe all will be LDS. Also, what's most important is that we fulfill what we're all here to do. All of us have important roles to fill, whether we're mentioned in scripture or not, we're all on unique missions to some extent.Jacob 5:61 Wherefore, go to, and call servants, that we may labor diligently with our might in the vineyard, that we may prepare the way, that I may bring forth again the natural fruit, which natural fruit is good and the most precious above all other fruit . . . 70 And it came to pass that the Lord of the vineyard sent his servant; and the servant went and did as the Lord had commanded him, and brought other servants; and they were few.
