Angels
In the New Earth, the world will no longer be under spiritual forces of evil. Satan and his evil host will be thrust into outer darkness forever.
12 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. Eph. 6:12, NIV
5 It is not to angels that he has subjected the world to come, about which we are speaking. Heb. 2:5, NIV
