Charles Ellicott Commentary 1 Corinthians 15:53

"For this corruptible must put on incorruption, and this mortal must put on immortality." — 1 Corinthians 15:53 (ASV)

For this corruptible must . . .—Here again is repeated the truth of 1 Corinthians 15:50, which shows the absolute necessity for a change in the nature of the resurrection body. There is, however, an additional thought introduced here. Not only must the resurrection body be suited to the condition but also to the duration of the new life. As a spiritual body, it will be adapted to the needs of a spiritual state; and as an immortal and incorruptible body, it will be adapted to a life which is everlasting.
