Your absolutist reasoning isn’t too consistent and certainly not so helpful to your cause… consider the implications of your logic:
Do YOU sin? If yes, is this not indicative that YOU “who sin are not submitting to God” QED… YOU are an enemy of God! THAT at least IF you are consistent is the outcome of your position. What then does that do for any claim to being “in Christ” – can such be even possible according to your position??
Again qaz, putting it simply… as a prêterist, so assuming you believe Paul’s “the last enemy” was “destroyed” as per Christ’s parousia… HOW is it you say there are yet MORE enemies PAST this death and this event? IOW… can you explain what “the last enemy to be destroyed is death” means to you IF it doesn’t mean the total desolation of that which to that point had separated man from God.
