'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.

(Isaiah 41:5) The isles and the ends of the earth, in the Word, signify people removed from the truths and goods of the church, because they do not have the Word and are thus in ignorance.
