'The first resurrection,' mentioned in Revelation 20:5, 6, does not mean a first resurrection, but the essence and primary part of resurrection, which is salvation and eternal life. There is only one resurrection to life. A second does not happen, and is not mentioned anywhere in the Bible.

2882. The main reason why a person believes that he has no freedom is his awareness that he, of himself, is incapable of doing what is good and thinking what is true. But let him not also believe that anyone ever has or has had of himself any freedom to think what is true and to do what is good. Not even those people had that freedom of themselves who, because they were utterly blameless, were called the image and likeness of God. But all freedom to think the truth of faith and to do a good deed of charity flows in from the Lord. The Lord is Good itself and Truth itself, and consequently their fountainhead. All angels possess that freedom and indeed the perception itself that all that has been said here is so. Inmost angels perceive how much comes from the Lord and how much from themselves, but that insofar as it comes from the Lord they know happiness and insofar as it comes from themselves they do not.
