Resurrection, the first
'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.

Heaven and Hell #140
140. Since the Lord as the sun is divine love, and divine love is the essential divine good, the divine that emanates from him - his divine nature in heaven - is called divine truth for the sake of clarity, even though it is divine good united to divine truth. This divine truth is what is called "the holy" that emanates from him.
