In regards to chapter 7 in Romans. The Christian walk is a battle of the old man vs the new. The old man (the "flesh", the sin nature) still exists, as Paul wrote.
However the beginning of chapter eight should actually be in the same chapter as seven. It is a continuation of Paul's testimony. Paul states he hath been made free from the law of sin and death. He is no longer in captivity to the Law of which was in his members; he is in the Spirit in Christ because Jesus came in the likeness of sinful flesh and condemned sin in the flesh; His flesh. That the righteousness of the law can be fulfilled in him (us). For Jesus Christ his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed. So be healed and go and sin no more.For if after we have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, we are again entangled therein, and overcome, the latter end is worse with them than the beginning.
(1Pe 2:24; 2Pe 2:20)
There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. For the law of the Spirit of life in Christ Jesus hath made me (Paul) free from the law of sin and death. For what the law could not do (in Paul's mind), in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.(Rom 8:1-4)
Please notice in that there in only no condemnation if we are walking in the Spirit and that Jesus condemned sin; taking it away; nailing it to the cross that the righteousness be fulfilled (completely filled ) in us.
