Expounding on the words of Isaiah, Paul taught, Death is swallowed up in victory, O death, where is thy sting? O grave, where is thy victory? The sting of death is sin; and the strength of sin is the law. But thanks be to God, which giveth us the victory through our Lord Jesus Christ (1 Cor 15:54-57). With a great knowledge of the scriptures, Aaron teaches the same doctrine as it was taught by Abinadi (Mosiah 16:8).
To the Savior, death is the enemy—both physical death and spiritual death. His pre-mortal assignment and foreordination were to destroy these two mortal enemies. After the Millenium and the short season which is to follow, the Savior will destroy all his enemies. His greatest enemies, of course, are sin and death. Paul explains, Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority, and power. For he must reign, till he hath put all enemies under his feet. The last enemy that shall be destroyed is death. For he hath put all things under his feet (1 Cor 15:24-27, italics added). Then will be the time when the grave shall have no victory, and…the sting of death should be swallowed up in the hopes of glory.
Commentary on Mosiah 16:8 describes four ways in which the sting of death is swallowed up in Christ.
