1 Nephi 12:16-19 In chapter 12, Nephi is permitted to view the future generation of his posterity in the promised land. When I visualize the great and spacious building that is upheld by the vain imaginations of the world, I note that there is no foundation, or that "it stood as it were in the air, high above the earth," ( 1 Nephi 8:26 ). A classic depiction of this illustrates this very well. I don't know that the scriptures mention anything about the lack of a foundation, but that it is upheld by vain imaginations suggest that these intangible nothings are the foundation of this very large building. Or in other words, there is no foundation. Then it is also interesting to note that there is no easy road between this great edifice of nothingness and the strait and narrow path of righteousness. The two are separated by a gulf of misery which consumes many.
