good question.
gal5;4 which talks about "have crucified the flesh"
Have crucified the flesh” is in the aorist tense, suggesting an action that took place in the past. This does not refer to self-crucifixion or self-mortification, but rather to Christians identifying with Christ’s death. A parallel passage may be found in
Romans 6:6 and
11, which state, “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...Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord” (see note 6 at
Romans 6:4 and note 7 at
Romans 6:6).
Victory over the flesh with its passions and lusts has already been provided for us by Christ through His death. We simply have to appropriate this truth by faith instead of self-effort.
Andrew Wommack's Living Commentary.
I will add to this by saying in Romans 6:6 the term "that the body of sin might be done away with/destroyed.." this word "to be done away with/destroyed ) in greek is " to make idle or useless"
So sin is still in the flesh in our body but is idle or useless to harm us or to be held by it..hence we are no more slaves to sin ( the parasite ) noun.
there is a big difference between the noun "sin" which is in the flesh ( like a parasite )..the sin principal is another term I have seen used...."sinning" are the sins you commit..it's a verb..an action..a "doing".
