1st Corinthians 15:51

48 Those who are of the earth are like the man who was from the earth: and those who are of heaven are like the one from heaven.

49 And in the same way as we have taken on us the image of the man from the earth, so we will take on us the image of the one from heaven.

50 Now I say this, my brothers, that it is not possible for flesh and blood to have a part in the kingdom of God; and death may not have a part in life.

51 See, I am giving you the revelation of a secret: we will not all come to the sleep of death, but we will all be changed.

52 In a second, in the shutting of an eye, at the sound of the last horn: for at that sound the dead will come again, free for ever from the power of death, and we will be changed.

53 For this body which comes to destruction will be made free from the power of death, and the man who is under the power of death will put on eternal life.

54 But when this has taken place, then that which was said in the Writings will come true, Death is overcome by life.
