'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.

275. The angels in the same heaven, or in the same society of heaven, are not all in like wisdom; their wisdom differs. Those at the center are in the greatest wisdom, and those round about even to the borders are in less wisdom. The decrease of wisdom in accord with the distance from the center is like the decrease of light verging to shade (see 43 and 128). Their light is in the same degree as their wisdom, since the light of heaven is the Divine wisdom, and everyone is in light in the measure of his reception of wisdom. Respecting the light of heaven and the varying kinds of reception of it see above (126-132).
