What does it mean that this corruptible must put on incorruption and this mortal must put on immortality?
At the last trump, the dead are raised incorruptible and living believers are changed in a moment. The corruptible puts on incorruption, and the mortal body prone to death puts on immortality. It means losing the flesh-and-blood concept and becoming flesh and bone activated by the Spirit.
Les explains that this change takes place at the last trump, in a moment, in the twinkling of an eye. The trumpet shall sound, the dead shall be raised incorruptible, and those who are alive and remain shall be changed. He ties this to the earlier statement that what was sown in corruption will be raised in incorruption. Verse 53 means the corruptible must put on incorruption, and the mortal body prone to death must put on immortality. According to Les, it must lose the flesh-and-blood concept and become flesh and bone activated by the Spirit. He also notes that the word “trumpet” is what throws a curve at so many people.
For this corruptible must put on incorruption, and this mortal must put on immortality.
