Book of Mormon - 1 Nephi 22:17

Feb 7, 2010: Nephi says the righteous will be saved, "even if it so be as by fire." I wonder what exactly he means by that. The first thought that came to mind is that the righteous will go through hard times and many "refiners fires" but will be blessed and saved at the last day. It won't be easy but if we prevail and go through the fire we will triumph. Do you think that is what Nephi meant? I think my musings have some relevance, at least.
