Romans 8:16-21

The Spirit Himself testifies and confirms together with our spirit [assuring us] that we [believers] are children of God. And if [we are His] children, [then we are His] heirs also: heirs of God and fellow heirs with Christ [sharing His spiritual blessing and inheritance], if indeed we share in His suffering so that we may also share in His glory. [John 17:24; Gal 3:29; 4:7; Eph 1:3, 11; 3:6; Heb 6:12] For I consider [from the standpoint of faith] that the sufferings of the present life are not worthy to be compared with the glory that is about to be revealed to us and in us! For [even the whole] creation [all nature] waits eagerly for the children of God to be revealed. For the creation was subjected to frustration and futility, not willingly [because of some intentional fault on its part], but by the will of Him who subjected it, in hope [Eccl 1:2] that the creation itself will also be freed from its bondage to decay [and gain entrance] into the glorious freedom of the children of God.
