“The creation itself also will be set free from enslavement to corruption and have the glorious freedom of the children of God.” (Rom. 8:19-21) “The creation” refers to mankind with the earthly hope, those who will benefit from “the revealing” of God’s spirit-anointed sons.

18. How will freedom increase for obedient mankind, and what freedom will they finally enjoy?

¹⁸ Redeemed mankind will then experience a completely new freedom​—freedom from the influence of Satan and the demons. (Rev. 20:1-3) What a relief that will be! Thereafter, Christ’s 144,000 fellow kings and priests will continue to liberate mankind by progressively applying the benefits of the ransom sacrifice until Adamic sin and imperfection have been fully erased. (Rev. 5:9, 10) Having proved faithful even under test, humans will have attained the very perfection of freedom that Jehovah has purposed for them​—“the glorious freedom of the children of God.” Think! No longer will you struggle to do what is right in God’s eyes, for your entire organism will have been perfected and your personality will have been fully transformed according to God’s image.
