1 Corinthians 15:51-53

But look! I tell you this secret: We will not all sleep in death, but we will all be changed. It will take only a second—as quickly as an eye blinks—when the last trumpet sounds. The trumpet will sound, and those who have died will be raised to live forever, and we will all be changed. This body that can be destroyed must clothe itself with something that can never be destroyed. And this body that dies must clothe itself with something that can never die.
