Military action undertaken in self-defense is certainly justifiable (Alma 48:14–15, 23–25; 53:10–17), so we are made to appreciate just how great a sacrifice the Anti-Nephi-Lehies made by burying their weapons of war. Some have wondered if this act gave rise to the Native-American tradition of “burying the hatchet” as a sign of making peace. These amazing people would rather have their own lives taken than take another’s life. They were firm in their convictions. God wants us to believe, then know, then remain firm. On the desirability of the divine attribute of firmness, see commentary at Jacob 3:1–2.
Thus we see that death can be a blessing to the righteous and also how the death of righteous souls can be a blessing to the living.
