Now the Lord begins to answer Alma's question.
The ultimate answer is not part of the immediate world, but of the eternities, and that is the reasons that the Lord has explained eternal consequences. Understanding the nature of the eternal consequences makes the temporal consequences more clear.
Since these dissenters "will not hear my voice," they are clearly not the Lord's "sheep" and therefore are not part of the church. They are not part of this "relocated" covenant. With the Abrahamic and Benjaminic covenants relocated to the authority of the church rather than assigned to the entire community, these dissenters are not part of the covenant, and receive none of the covenantal blessings.
