It is because you have referred to the flesh as if you believe it is to be glorified or immortalized (not that you said it that way--but rather that you seem to support that commonly believed doctrine).
Both Paul and I say of "the flesh" that we are NOT IN THE FLESH, so you are not understanding a thing I've said, not even Paul. The flesh is called "the old man" and when we truly repent, the flesh is crucified. That means it is DEAD, not glorified nor immortalized in sin! The flesh is what the church calls "carnal nature," or "sin nature." What is resurrected is a brand new
clean human nature inside of us, a new spirit and new soul without sin.
That is here and now, and yes, the new spirit and soul Jesus creates in us is righteous, and He takes it through the long process of glorification and is immortal. The Church erroneously calls that process "sanctification." No, it is "glorification." Sanctification is past tense. It just means we are set apart for holiness when we were first washed and justified. See what Paul says,
1 Corinthians 6:11b "But you
were washed, but you
were sanctified, but you
were justified in the name of the Lord Jesus and by the Spirit of our God."
Paul doesn't even mention it in Romans 8:30, but he DOES glorified the proper name of the process of maturing all the fruit of the Spirit over a long period of time, making us truly into the image of Jesus.
Romans 8:29-30 "For whom He foreknew, He also predestined
to be conformed to the image of His Son, that He might be the firstborn among many brethren. 30 Moreover whom He predestined, these He also called; whom He called, these He also justified; and whom He justified, these He also
glorified" That is now, not after we are dead as is falsely taught.
Here is another past tense reference of Paul's, this time to "the flesh."
Romans 7:5-6, "For
when we were in the flesh, the sinful passions which were aroused by the law were at work in our members to bear fruit to death. 6
But now we have been delivered from the law
, having died to what we were held by, so that we should serve in the newness of the Spirit and not
in the oldness of the letter."
That is not our death, but the death of the sin nature inside. Here is where Paul first teaches this:
Romans 6:5-7 "For if we have been united together in the likeness of His death, certainly we also shall be
in the likeness of
His resurrection, 6 knowing this, that our old man was crucified with
Him, that
the body of sin might be done away with, ("body" is like a writer's body of works, or the Beatles whole catalog of works); it just means "whole," or "all unrighteousness,") that we should no longer be slaves of sin. 7 For he who has died has been
freed from sin.
