Revelation 20:6

in order that I may attain to the resurrection from the dead.

and He has made us to be a kingdom, priests to His God and Father—to Him be the glory and the might forever and ever. Amen.

‘He who has an ear, let him hear what the Spirit says to the churches. He who overcomes will never be hurt by the second death.’

And I heard a voice from heaven, saying, “Write, ‘Blessed are the dead who die in the Lord from now on!’” “Yes,” says the Spirit, “so that they may rest from their labors, for their deeds follow with them.”

Then I saw thrones, and they sat on them, and judgment was given to them. And I saw the souls of those who had been beheaded because of their witness of Jesus and because of the word of God, and who also had not worshiped the beast or his image, and had not received the mark on their forehead and on their hand. And they came to life and reigned with Christ for a thousand years.

Then death and Hades were thrown into the lake of fire. This is the second death, the lake of fire.
