But it is our desire, brothers, that you may be certain about those who are sleeping; so that you may have no need for sorrow, as others have who are without hope. For if we have faith that Jesus underwent death and came back again, even so those who are sleeping will come again with him by God's power. For this we say to you by the word of the Lord, that we who are still living at the coming of the Lord, will not go before those who are sleeping.read more.
Because the Lord himself will come down from heaven with a word of authority, with the voice of the chief angel, with the sound of a horn: and the dead in Christ will come to life first; Then we who are still living will be taken up together with them into the clouds to see the Lord in the air: and so will we be for ever with the Lord.

Then will the King say to those on his right, Come, you who have the blessing of my Father, into the kingdom made ready for you before the world was: For I was in need of food, and you gave it to me: I was in need of drink, and you gave it to me: I was wandering, and you took me in; I had no clothing, and you gave it to me: when I was ill, or in prison, you came to me. Then will the upright make answer to him, saying, Lord, when did we see you in need of food, and give it to you? or in need of drink, and give it to you? And when did we see you wandering, and take you in? or without clothing, and give it to you? And when did we see you ill, or in prison, and come to you? And the King will make answer and say to them, Truly I say to you, Because you did it to the least of these my brothers, you did it to me. Then will he say to those on the left, Go from me, you cursed ones, into the eternal fire which is ready for the Evil One and his angels: For I was in need of food, and you gave it not to me; I was in need of drink, and you gave it not to me: I was wandering, and you took me not in; without clothing, and you gave me no clothing; ill, and in prison, and you came not to me. Then will they make answer, saying, Lord, when did we see you in need of food or drink, or wandering, or without clothing, or ill, or in prison, and did not take care of you? Then will he make answer to them, saying, Truly I say to you, Because you did it not to the least of these, you did it not to me. And these will go away into eternal punishment; but the upright into eternal life.

And I said to him, My lord, you have knowledge. And he said to me, These are they who came through the great testing, and their robes have been washed and made white in the blood of the Lamb.
