Alma and the Waters of Mormon

I just finished posting my claim that many of what we traditionally consider King Benjamin's exhortations are in fact promised blessings from accessing the power of the atonement, when I found myself in Sunday School reading Alma exhorting the same sorts of things:   be willing to bear one another's burdens, mourn with those who mourn, comfort those that stand in need of comfort. I thought, "Huh, maybe its not as simple as I thought?" But after a quick check I found the following scripture immediately before describing an important part of the process these people had gone through.

Mosiah 18:7 And it came to pass after many days there were a goodly number gathered together at the place of Mormon, to hear the words of Alma. Yea all were gathered together that believed on his word, to hear him. And he did teach them, and did preach unto them repentance, and redemption, and faith on the Lord.

This is Mormon abridging. I'm assuming after having laid out all of King Benjamins words about repentance, redemption and faith on the Lord, and then immediately laying out all of Abinidi's words on the same topic, he felt he didn't need to specify Alma's words. We should have gotten it. I wonder if Mormon is saddened to be the name of the people that have so diligently avoided what is clearly one of his most precious ideas - the atonement.
