'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.

2848. 'Your seed' means spiritual people who, having that good within them that springs from faith, are saved by the Lord's Divine Human. This is clear from the meaning of 'seed' as faith that is the expression of charity, dealt with in 1025, 1447, 1610, 1941, or what amounts to the same, those members of the human race who possess faith that is the expression of charity, that is, who are spiritual people. They are also called by the Lord 'the seed' and 'the sons of the kingdom', in Matthew,

He who sows the good seed is the Son of Man, but the seed are the sons of the kingdom. Matthew 13:37-38.
