"O death, where is thy sting?"

In 1 Corinthians 15, Paul teaches the Saints about the Resurrection of Jesus Christ after false prophets taught that there was no resurrection of the dead. There is one great message of the Savior's Resurrection: hope. His Resurrection offers us hope in being reunited with our loved ones who have passed on and hope in the end of our struggling and sorrow.

His Resurrection gives us "victory over death." Because of the Fall, all men will face physical death. But, because of Christ, we know that we can be made alive again through His Resurrection, which makes our own resurrection possible. In verse 22, as Paul explains it, "For as in Adam we all die, even so in Christ shall all be made alive." And, later in the chapter, we read, "Death is swallowed up in victory. O death, where is thy sting? O grave, where is thy victory? . . . thanks be to God, which giveth us the victory through our Lord Jesus Christ" (verses 54 - 57). Death is not the end and it is not final. It is only a small part of our Heavenly Father's Plan.

The Resurrection of Christ allows us to know that there is an end to our suffering and sorrow, even an end to the grief that comes with the death of loved ones. Elder Joseph B. Wirthlin stated:

“. . . when the Savior rose from the tomb, He did something no one had ever done. He did something no one else could do. He broke the bonds of death, not only for Himself but for all who have ever lived—the just and the unjust.

When Christ rose from the grave, becoming the firstfruits of the Resurrection, He made that gift available to all. And with that sublime act, He softened the devastating, consuming sorrow that gnaws at the souls of those who have lost precious loved ones.”
