Revelation 14:13

Then I heard a voice from heaven say, "Write: Blessed are the dead who die in the Lord from now on." "Yes," says the Spirit, "they will rest from their labor, for their deeds will follow them."

Blessed are the dead
Revelation 20:6 Blessed and holy are those who have part in the first resurrection. The second death has no power over them, but they will be priests of God and of Christ and will reign with him for a thousand years.

who die in the Lord from now on
1 Corinthians 15:51-53 Listen, I tell you a mystery: We will not all sleep, but we will all be changed--in a flash, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we will be changed. For the perishable must clothe itself with the imperishable, and the mortal with immortality.
1 Thessalonians 4:16 For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first.

says the Spirit
Revelation 2:7 "He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes, I will give the right to eat from the tree of life, which is in the paradise of God."
Revelation 22:17 The Spirit and the bride say, "Come!" And let him who hears say, "Come!" Whoever is thirsty, let him come; and whoever wishes, let him take the free gift of the water of life.

rest from their labor
Hebrews 4:9 There remains, then, a Sabbath-rest for the people of God.
Revelation 6:11 Then each of them was given a white robe, and they were told to wait a little longer until the number of their fellow servants and brothers who were to be killed as they had been was completed.

for their deeds will follow them
1 Corinthians 3:11-15 For no one can lay any foundation other than the one already laid, which is Jesus Christ. If any man builds on this foundation using gold, silver, costly stones, wood, hay or straw, his work will be shown for what it is, because the Day will bring it to light. It will be revealed with fire, and the fire will test the quality of each man's work. If what he has built survives, he will receive his reward. If it is burned up, he will suffer loss; he himself will be saved, but only as one escaping through the flames.
