'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.

1276. Spirits in the world of spirits, and angels in heaven, are positioned as follows: Angels are on the Lord's right and evil spirits on His left. At the front are those of an intermediate kind, while the wicked are at the back. Overhead are those who are haughty and aspire to high things, and underfoot are the hells which correspond to those who are on high. In this way the positions of all are fixed in relation to the Lord, as to every direction and degree of height, horizontally and vertically, and in every oblique direction. Their positions remain constant, eternally the same. The heavens constitute so to speak one human being, who is therefore called the Grand Man, to which everything in the human being also corresponds. This correspondence will in the Lord's Divine mercy be dealt with later on. Consequently the positioning of everything around each angel is similar, and around each person to whom heaven is opened by the Lord. This is an effect of the Lord's presence, and could not happen if the Lord were not omnipresent in heaven.
