This describes the elect, those who were called in their lifetime:
Rev 20:4 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 testimony of Jesus and because of the word of God, and those who 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.
The next verse refers to the rest, who were not called in their lifetime:
Rev 20:5 The rest of the dead did not come to life until the thousand years were completed..
Back to the elect:
Rev 20:6 Blessed and holy is the one who has a part in the first resurrection; over these the second death has no power, but they will be priests of God and of Christ and will reign with Him for a thousand years.
And then back to the first chance for these people:
Rev 20:12 And I saw the dead, the great and the small, standing before the throne, and books were opened; and another book was opened, which is the book of life; and the dead were judged from the things which were written in the books, according to their deeds
Calvinists generally don't accept this because it seems like they believe that they are the elect and disregard that anyone else gets a later calling.
Doug that says noting about a second chance not one word...
