1 Corinthians 15:53 Meaning

51Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,

52In 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.

53For this corruptible must put on incorruption, and this mortal must put on immortality.

54So 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.

55O death, where is thy sting? O grave, where is thy victory?
