'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.

2883. To acquire a heavenly proprium therefore man needs to do good from himself and to think truth from himself. But still he needs to know, and when he has been reformed, to think and believe, that everything good and everything true comes from the Lord, even the least trace of all, and to think and believe this because it is so. Yet a person is allowed to suppose that he acts from himself in order that good and truth may become as if they were his own.
