Philippians 3:21
15 Therefore let those of us who are “perfect” embrace this point of view. If you think otherwise, God will reveal to you the error of your ways. 16 Nevertheless, let us live up to the standard that we have already attained. 17 Be imitators of me, brothers and sisters, and watch carefully those who are living this way, just as you have us as an example. 18 For many live, about whom I have often told you, and now, with tears, I tell you that they are the enemies of the cross of Christ. 19 Their end is destruction, their god is the belly, they exult in their shame, and they think about earthly things. 20 But our citizenship is in heaven—and we also eagerly await a savior from there, the Lord Jesus Christ, 21 who will transform these humble bodies of ours into the likeness of his glorious body by means of that power by which he is able to subject all things to himself.
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. 5 When therefore they see those, over whom they are now exalted, (but) who shall then be exalted and glorified more than they, they shall respectively be transformed, the latter into the splendour of angels, and the former shall yet more waste away in wonder at the visions and in the beholding of the forms. 6 For they shall first behold and afterwards depart to be tormented.
Notes and References
"... The politeuma in Philippians 3:20–21 also acts politically when sending out a savior (σωτῆρ). The believers are desperately awaiting him “from there” (ἐξ οὗ). Saviors are gods, men, and women, who save people or communities in times of crisis and help to improve living conditions. Human saviors act by commission of the gods. The political leader Aratus, for example, is praised as a savior before the savior Gods “because to thy native city thou hast brought a sacred and heavenly reign of law.” ... The saving act makes the human savior the agent of divine power. Politeumata send out citizens on rescue missions ... who the other citizens of the heavenly politeuma are is not mentioned. Because the politeuma already acts by sending the σωτήρ, it is not very likely that only the future or exiled members, the Philippians, are in view. A politeuma of angels is more probably in mind, as in the case of the Dead Sea Scrolls. In any case, the σωτήρ Jesus Christ clothes the citizens to be saved with an appropriate heavenly garment that represents his body of glory ... (Compare Daniel 12:2–3; 1 Enoch 104:2, 4; 4 Ezra 7:97, 125 ... see 1 Enoch 108:11; 2 Baruch 51:1-10; Ascension of Isaiah 8:26; 9:9) ..."
