If I did it was mistaken. Sorry. I’m looking for the Christian theological response to can (a) Hiller repent, accept Jesus, and earn the Christian eternal kingdom?
I consider myself a Christian (probably not a very good one, I have a huge temper) and I will try to answer your question to the best of my ability.
I don’t think that Hitler was mentally or emotionally capable of the type of repentance your talking about.
The thing you have to remember is that Hitler considered himself the FUHRER, and as the ultimate authority of all of Germany, all his conquered lands, and all the people therein.
In order to truly repent you first have to believe there is a power greater, higher than your own.
I don’t personally think that a personality like Hitler could even conceive of a person or thing greater than himself.
He had for years been treated as a god in his own country and only had to look around to see the adoration of his worshippers
In Hitler’s mind there was no higher authority than himself, so how, and who do you ask for absolution from?
He couldn’t ask it from himself, as what he did and caused to be done, he considered right.
He couldn’t ask it from JESUS because he believed he outranked JESUS.
He couldn’t ask it from GOD because he was “god” as far as he was concerned.
He could only end his live and go into OBLIVION!
Cannot imagine how I missed seeing this thread, and your important question--which seemingly never received an on-target answer. At this late date....
To restate your question:
Aside from blaspheming the Holy Spirit (the "unpardonable sin", Mt.12, Mk.3, Lk.12), the short answer is "No". Whether Hitler himself crossed that line, only God knows.
The key is understanding that "all have sinned" (Ro.3:23). Indeed, Jesus convicted all of us as serial murderers (just like ol' Adolf) when he equated anger with murder (Mt.5:21-22). Yet Jesus intervened and paid for all those murders, and all other sin, at Calvary.
Remarkably, Scripture provides us with a Hitler-like example of a national leader who murdered millions but later was redeemed: Nebuchadnezzar. It took seven years of insanity to effect his repentance, but the Holy Spirit can do that. I doubt He did it for Hitler, but that's the game: more enter hell than heaven.
