In Alma 15:15, we read about the hard-hearted and stiffnecked people of Ammonihah, with this added detail:
...for they were of the profession of Nehor, and did not believe in the repentance of their sins.
Remember Nehor, back from Alma 1? In that chapter he is introduced like this:
4 And he also testified unto the people that all mankind should be saved at the last day, and that they need not fear nor tremble, but that they might lift up their heads and rejoice; for the Lord had created all men, and had also redeemed all men; and, in the end, all men should have eternal life.
Like many examples of internal consistency in the Book of Mormon, this is one that is very subtle and draws no attention to itself.
