I believe a literal resurrection of believers already took place in 70AD.
Since 70AD, believers who physically die, instantly received a new glorified body, and enter the kingdom...
Paul explains it a few verses earlier:
(Rom 8:10-11) But if Christ is in you, then even though your body is subject to death because of sin, the Spirit gives life because of righteousness. 11 And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies because of his Spirit who lives in you.
Sheesh - talk about your reading things into passages, Tet.
Never mind the context of Romans 6-8.
The sense of those three chapters as to this issue being the fact that because He Who raised up Christ from the dead lives in the Believer, He will will enable said Believer to overcome his or her mortal body's inability to overcome the flesh.
Romans 6:
6 Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
9 Knowing that Christ being raised from the dead dieth no more; death hath no more dominion over him.
How? Merely by walking in the Spirit.
How is this walking in the Spirit appropriated?
By reckoning - taking it as fact - that what the Spirit is declaring through Paul as to the Believer's reality in the Lord as to this issue IS the Believer's reality.
Romans 6:
11 Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.
12 Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof.
He is talking Galatians 2:20's Believer's reality - "I
am crucified with Christ: nevertheless I live;
yet not I, but Christ liveth in me: and the life
which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me."
