In Lehi’s dream we find there are 3 distinct groups of people. The 1st group wanders aimlessly around in the mist of darkness (temptations) until they find themselves in the great and spacious building among the riotous living of the world.
The 2nd group takes hold of the iron rod (the word of God) and clings to it from time to time until they reach the tree of life (the love of God) and partake of its fruit (eternal life). This 2nd group unfortunately turns from the fruit ashamed after hearkening to the 1st group in the great and spacious building, who are scoffing at them from a distance. This great and spacious building (pride of the world) eventually fell and great was the fall thereof.
Lastly, the 3rd group presses forward “continually holding fast to the rod of iron” until they came forth, fell down, rose up and partook of the fruit of the tree. This 3rd group remained due to their continual sacrifice in enduring to the end, so much so that they fell down with exhaustion of physical, mental, and spiritual strength. That sacrifice sealed their place in receiving the love of God and eternal life.
What sacrifice will we make? The choice is ever placed before us. -1 Nephi Chapter 8
