Passage
For this corruptible must put on incorruption, and this mortal must put on immortality.
For this corruptible must put on incorruption, and this mortal must put on immortality.
1 Corinthians 15:51 Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
1 Corinthians 15:52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised 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 So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
1 Corinthians 15:55 O death, where is thy sting? O grave, where is thy victory?
The verse centers on "corruptible", "must", "incorruption", "mortal", and "immortality". It is saying that the verse draws attention to "corruptible" and "must", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 52's "In a moment in the twinkling of..." into verse 54's "So when this corruptible shall have put...", so "corruptible" and "must" 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 "corruptible" and "must" with trust shaped by these words, not by a vague optimism outside the passage.
