As Alma notes, Amulek concentrated on the physical death and resurrection. Alma will discuss the more spiritual aspects of the atonement, the need for repentance. Where the physical resurrection is a free gift to all, our ultimate salvation depends upon each individual.
As Alma sets up his discourse, he begins by placing the resurrected persons before the bar of God. At that time he speaks of having hard hearts, and if the hearts are hard against the word, then we should be condemned. As Alma will explain later, we cannot hope that the change of location will automatically make a change in our hearts. What our soul is upon death rises with us, and continues to demonstrate our learned reaction to the gospel (Alma 34:4).
