The sons of Perdition are those for whom the redemption has no effect. The terms resurrection and redemption are different, and it is important to underscore that they are resurrected and thereby overcome physical death. But they are never redeemed (DC 76:38). This means that they cannot dwell with God. They suffer the second spiritual death. Even those of the telestial kingdom will be blessed with the ministration of the Holy Ghost (DC 76:86), but not the sons of Perdition. They are barely holy enough to dwell with Satan. Therefore if that man repenteth not, and remaineth and dieth an enemy to God, the demands of divine justice do awaken his immortal soul to a lively sense of his own guilt, which doth cause him to shrink from the presence of the Lord, and doth fill his breast with guilt, and pain, and anguish, which is like an unquenchable fire, whose flame ascendeth up forever and ever. And now I say unto you, that mercy hath no claim on that man; therefore his final doom is to endure a never-ending torment. (Mosiah 2:38-39)
