I like to get back to the topic & relevant passage:
Romans 8:18-23 NKJV,
From Suffering to Glory
18 For I consider that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us. 19 For the earnest expectation of the creation eagerly waits for the revealing of the sons of God. 20 For the creation was subjected to futility, not willingly, but because of Him who subjected it in hope; 21 because the creation itself also will be delivered from the bondage of corruption into the glorious liberty of the children of God. 22 For we know that the whole creation groans and labors with birth pangs together until now. 23 Not only that, but we also who have the firstfruits of the Spirit, even we ourselves groan within ourselves, eagerly waiting for the adoption, the redemption of our body.
It is raised a spiritual body. The corporate "body" of the church. Jew & Gentile in Christ. True Israel. Their "salvation was nigh at hand." This is the "change" for those on earth at Christ's coming. The 1st resurrection were "priests of God" & reigned on earth.(Rev.5)
We cannot mistake the exulting anticipation expressed by St.Paul of the coming day of deliverance from the sufferings & miseries of the present- a deliverance which was at hand, & not far off. There was a day of redemption coming which would bring freedom & glory to the sons of God- in the benefits of which the whole creation would participate.
The 1st point that demands attention is the distinct indication of the nearness of this coming glory. This is entirely lost sight of in modern authorized versions even & similarly ignored by almost all commentators.
The Greek & proper frorce of the language says "the glory which is about to be revealed, which soon shall be revealed."
The 'coming glory' is the counterpart or antithesis of the 'coming wrath' ~ different aspects of the same great event: for the Parousia, which was the revelation of glory to the sons of God, was the revelation of the day of wrath to His enemies (Romans 2:5,7)
The apostle does not so mock them with hope deferred- it would be a cold comfort for men writhing under the anguish of their sufferings- to tell them of a period of future age which would bring them compensation for their present distress.
The whole creation is moral & thoughtful creation (man) awaiting the manifestation of "the sons of God."
And these apostles & disciples of Christ were indeed who the whole creation was waiting for.
To Paul, in his view, a great event was about to take place- the Lord was about to come, according to His promise, to exercise His kingly power, to give recompense & salvation to His ppl, & to tread His enemies under His feet.
But the Parousia was to bring more than this. It marked a great epoch in the divine government of man. It terminated the period of exclusive privilege of Israel. It dissolved the covenant-bond between Jehovah & the Jewish ppl- & made way for a better covenant which embraced all mankind.
