None of the above verses teach that believers have the victory over sin in this life, nor do they teach that believes can resist temptation for any length of time.This has been an enjoyable conversation, thank you for that
You’re right that Romans 7 describes a real lifelong conflict — Paul never says the flesh disappears — but your conclusion that “we never have real victory in this life” contradicts the very passages you’re using.
Romans 7 shows indwelling sin remains;
Romans 8 shows indwelling sin does not reign.
Paul says the regenerate “are not in the flesh” (Rom 8:9),
“the law of the Spirit of life has set you free” (8:2), and
“sin shall not have dominion over you” (Rom 6:14).
That is not perfectionism; it is Spirit‑produced victory in the war, not the removal of the war.
Mortification (Rom 8:13) proves sin remains, but the command “put to death” proves the Spirit actually enables obedience.
Groaning (Rom 8:23) proves we await glorification, but groaning is not defeat — it is longing from people who already “walk in the Spirit” (Gal 5:16) and actually “renounce ungodliness” because grace trains them (Titus 2:12).
The golden chain (Rom 8:29–30) shows final victory is future, but it never says present victory is nonexistent; it says present sanctification is real, progressive, and Spirit‑empowered.
So the biblical tension is simple: the war is lifelong (Rom 7), but the Spirit gives real victories now (Rom 6; Rom 8; Gal 5; Titus 2).
The mistake is treating Romans 7 as the final word instead of the setup for Romans 8’s Spirit logic.
Whilst the regenerate are not in the flesh, we still sin every single day and we will continue to sin every single day for the rest of our lives. We don't sin by choice, we sin because we still retain some of our sin nature.
Believers don't always walk in the Spirit, we resist the Spirit everyday when we wilfully sin. If we say we have no sin, then the truth is not in us. The truth is the Lord Himself, His Spirit is not in us if we deny the fact that we sin everyday.
You can put sin to death as often as you like, but it will keep rearing it's ugly head everyday and it's death is never permanent in this life. Present individual victories are only temporary, so it's not a question of victory being non-existent.
