Passage
And when this mortal hath put on immortality, then shall come to pass the saying that is written: Death is swallowed up in victory.
And when this mortal hath put on immortality, then shall come to pass the saying that is written: Death is swallowed up in victory.
1 Corinthians 15:52 In a moment, in the twinkling of an eye, at the last trumpet: for the trumpet shall sound and the dead shall rise again incorruptible. And we shall be changed.
1 Corinthians 15:53 For this corruptible must put on incorruption: and this mortal must put on immortality.
1 Corinthians 15:54 And when this mortal hath put on immortality, then shall come to pass the saying that is written: Death is swallowed up in victory.
1 Corinthians 15:55 O death, where is thy victory? O death, where is thy sting?
1 Corinthians 15:56 Now the sting of death is sin: and the power of sin is the law.
The verse centers on "mortal", "hath", "immortality", "shall", "come", "pass", "saying", and "written". It is saying that the verse draws attention to "mortal" and "hath", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 53's "For this corruptible must put on incorruption..." into verse 55's "O death where is thy victory O...", so "mortal" and "hath" belong inside that flow. In 1 Corinthians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "mortal" and "hath" with trust shaped by these words, not by a vague optimism outside the passage.
