'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.

146. However, the regions in the heavens that make up the Lord's heavenly kingdom differ from those in the heavens that make up the Lord's spiritual kingdom. This is because to the angels in his heavenly kingdom the Lord looks like a sun, while to the angels in his spiritual kingdom he looks like a moon, and the east is where the Lord is seen.

The distance between the sun and the moon is thirty degrees, and the same alignment therefore holds true for the directions. The division of heaven into two kingdoms called the heavenly kingdom and the spiritual kingdom has been presented in its own chapter above (20-28), as has the Lord's looking like the sun in the heavenly kingdom and like the moon in the spiritual kingdom (118). Still, the directions are not rendered uncertain by this, since spiritual angels cannot rise up to the level of heavenly angels, nor the latter come down to the former (see 35 above).
