Romans 8:17
15 For you did not receive the spirit of slavery leading again to fear, but you received the Spirit of adoption, by whom we cry, “Abba, Father.” 16 The Spirit himself bears witness to our spirit that we are God’s children. 17 And if children, then heirs (namely, heirs of God and also fellow heirs with Christ)—if indeed we suffer with him so we may also be glorified with him. 18 For I consider that our present sufferings cannot even be compared to the coming glory that will be revealed to us. 19 For the creation eagerly waits for the revelation of the sons of God.
2 Baruch 51:3
Syriac Apocalypse of Baruch1 And it shall come to pass, when that appointed day has gone by, that then shall the aspect of those who are condemned be afterwards changed, and the glory of those who are justified. 2 For the aspect of those who now act wickedly shall become worse than it is, as they shall suffer torment. 3 Also (as for) the glory of those who have now been justified in My law, who have had understanding in their life, and who have planted in their heart the root of wisdom, then their splendour shall be glorified in changes, and the form of their face shall be turned into the light of their beauty, that they may be able to acquire and receive the world which does not die, which is then promised to them. 4 For over this above all shall those who come then lament, that they rejected My law, and stopped their ears that they might not hear wisdom or receive understanding.
Notes and References
"... The above interpretation of Romans 8:17 as introducing a description of a transformation of the children of God at the time of the parousia in 8:18–30 is supported by the use of “glory” in eschatological contexts in 4 Ezra and 2 Baruch. In the description of the experiences of the souls of the ungodly and the righteous after death in 4 Ezra 7:78–101, the term “glory” appears five times. As soon as the soul of a person leaves his or her body, it “adores the glory of the Most High” (7:78). Those who have not kept the laws of the Most High “wither with fear since they see the glory of the Most High, before whom they sinned now while they were alive, and before whom they are to be judged in the last times” (7:87), while those who have kept his laws “see with great joy the glory of him who receives them, for they shall have rest in seven orders” (7:91). While the first three mentions of glory in this passage establish it as a divine attribute, the latter part of the description of the “seven orders” of rest for the righteous looks forward to “the glory which awaits them in the last days” (7:95). The sixth order is “when it is shown to them how their face is to shine like the sun, and how they are to be made like the light of the stars, being incorruptible from then on” (7:97), and the seventh is confident joy, “for they hasten to behold the face of him whom they served in life and from whom they are to receive their reward when glorified” (7:98). Thus, although “glory” remains primarily a divine quality in 4 Ezra, this passage on the afterlife reveals that the righteous will partake in it in the last days ..."
