"But is now made manifest by the appearing of our Saviour Jesus Christ, who hath abolished death, and hath brought life and immortality to light through the gospel." (2 Timothy 1:10)
Most of us have read or heard the passage in 1 Corinthians 15:55-57 that directly challenges death and hell with the fact of the resurrected Christ and the promise of our own resurrection when He returns. There is no "sting" left in death and there is no law that overrides our salvation because our Lord Jesus has gained the victory.
Long ago, the great man Job faced his detractors with the confidence that "in my flesh shall I see God" (Job 19:26). The prophet Hosea, in the middle of difficult life demands and during a time of awful apostasy, heard the Lord promise those who were faithful, "I will ransom them from the power of the grave; I will redeem them from death: O death, I will be thy plagues; O grave, I will be thy destruction" (Hosea 13:14).
The good news of the implementation of God's eternal plan brought "life and immortality to light." All during the millennia of the Old Testament, fulfillment of God's actions were hinted at, through the sacrifices of the altar, and promised oftentimes in the utterances of the prophets. But when the Messiah became incarnate, "we beheld his glory, the glory as of the only begotten of the Father" (John 1:14).
The apostle John, whose gospel and letters consummate in the great Revelation disclosure, could say, "The life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us" (1 John 1:2). He who is life (John 11:25) promised, "He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life" (John 5:24).
