The 2 eternal dwelling places will be the lake of fire (for the wicked) and the new heavens and new earth (for God and the righteous).
The lake of fire will be the place of eternal punishment and separation from God for the wicked (demons and unbelievers).
Revelation 20:10: And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
The Unholy Trinity consists of the devil (Satan), beast (Antichrist), and false prophet (2nd beast); all 3 members are against God and will be cast into the lake of fire to suffer eternal punishment for their sins.
Revelation 20:15: And whosoever was not found written in the book of life was cast into the lake of fire.
Neither demons (unholy angels) nor unbelievers (unsaved humans) at the Great White Throne Judgment will have their names written in the book of life. They will be judged according to their works and cast into the lake of fire to suffer eternal punishment for their sins, along with the Unholy Trinity.
The new heavens and new earth will be God’s recreated universe for the righteous (Christians and holy angels).
Isaiah 65:17: For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind.
In this verse, God announces the new heavens and new earth, replacing the 1st heavens and 1st earth.
Revelation 21:1: And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.
When the 1st heavens and 1st earth pass away, the new heavens and new earth will replace them. Those whose names are written in the book of life will enjoy eternity with God on the new earth. Only God and good will be present; evil will be completely absent.
Revelation 21:7-8: He that overcometh shall inherit all things; and I will be his God; and he shall be my son.
But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.
Thank you for reading this article. May God bless you with eternal life with him, ultimately in the new heavens and new earth.
