'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.

122. We need to be fully aware, however, that when we are about to repent we need to turn to the Lord alone. If we turn only to God the Father we cannot be cleansed, nor if we turn to the Father for the sake of the Son or to the Son as merely human. There is only one God, and the Lord is that God because his divine and his human natures are one person, as I have explained in Teachings for the New Jerusalem on the Lord. To enable us to turn to the Lord alone when we are about to repent, the Lord instituted the Holy Supper, assuring forgiveness of sins to those who repent. The sacrament offers that assurance because during that Supper or Communion, each participant is kept focused on the Lord alone.
