YOu have a mental disorder such that when you read that 'this is the new covenant in my blood for the forgiveness of sins' then several things happen:
1, you see a Davidic theocracy just around the corner
2, this can't possibly be for the sins of mankind; no, God was going to crucify Christ or something else for Gentiles sins some other place or time
3, eternal can't be before time, before the creation of the world. No, it's so much 'smartypants' better to insult another believer in Christ and say that 'eternal' is AFTER the old covenant
I can't do anything about this mental disorder. You have to fix it.
