The first line of verse 20 has caught me attention this morning. There are deliberate preparations by their brethren to destroy the people of Anti-Nephi-Lehi. I think the Spirit is trying to tell me this morning that there are deliberate preparations in our day to destroy the righteous and righteousness. I feel it is more calculated and bent on destruction than any would realize. But if these had been converted to the Gospel of Christ, as brethren, they would not have been the opposition.
Now what happens here is a difficult story to think about and consider, but it is the account of selfless sacrifice even to the point of death, or laying down of one's own life, and the resultant conversion of more than a thousand of their brethren who openly opposed them on the battlefield.
The conclusion to this section is found in verse 27: "thus we see that the Lord worketh in many ways to the salvation of his people."
After prayer, I am caused to consider the repercussions of this sacrifice on their families. It strikes me that the accounts of the stripling warriors does not connect the two groups directly (those who had been slain and the fathers of the stripling warriors), but perhaps in part, this is why the account of the stripling warriors only makes reference to their mothers. It is very likely that some of their fathers were among those who had been slain.
