The “awful death” refers to the second death, which is a permanent death that prevents one from entering into exaltation: “The scriptures sometimes speak of salvation from the second death. The second death is the final spiritual death—being cut off from righteousness and denied a place in any kingdom of glory (see Alma 12:32; D&C 88:24). This second death will not come until the Final Judgment, and it will come to very few (see D&C 76:31–37). Almost every person who has ever lived on the earth is assured salvation from the second death (see D&C 76:40–45)” (True to the Faith, 153).
