“After the separation of body and spirit, which is the natural death, the wicked and ungodly die a second death, a spiritual death, meaning they are cast out of the presence of the Lord and are dead as pertaining to the things of righteousness. … (D. & C. 63:17–18.)
“But when those here designated have suffered for their own sins … they shall come forth in the second resurrection and receive their inheritance in the telestial kingdom. (D. & C. 76:103–106.) That is, the allotted period of their spiritual death shall cease: and all men, except the sons of perdition, shall receive their part in the kingdoms which are prepared” (McConkie, Doctrinal New Testament Commentary, 3:584–85).
