'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.

154. How the States of Angels in Heaven Change

By "the changes of angels' states," we mean their changes in regard to love and faith and therefore in regard to wisdom and intelligence - to the state of their life, that is. States are attributes of life and of matters that pertain to life; and since angelic life is a life of love and faith and thereby of wisdom and intelligence, states are attributes of these, and we talk about states of love and faith and states of wisdom and intelligence. Now we need to describe how these states change for angels.
