There are many verses that speak of atonement for the elect. There are also many verses that speak of atonement for all.

E.G.
John 1:29 (King James Version)29The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.

One can say he died for the world, because the world includes the elect, but the elect does not include the world. Some may say if he takes away the sins of the world then all will be saved. That would be a true assumption if one does not look at atonement as two fold. While Christ's death actually atones for sin, it is never applied apart from faith. Christ died for the whole world, but the whole world will not be saved because atonement is only applied to ones account by faith.

I agree in part.



he did atone for all sin, In fact scripture states he propitiated (
satisfied Gods wrath) not only our ( the elect ) sins, but the sins of
the whole world.



there sin will be forgiven them,, there one sin will not. the sin he did not make atonement for.



they will be condemned for unbelief, not for personal sin. Hitler's
sins were atoned for. If he repented and came to Christ he would be
saved, If he did not, he will not suffer damnation for the murders he
committed, but for rejecting the holy spirit and the conviction and
word he came to share with us.. namely Christ.

I have heard that understanding before, but I did not receive it based on other scriptures. Check these out and see what you think

“ And I saw the dead, the great and the small, standing before the throne. Then books were opened, and another book was opened – the book of life. So the dead were judged by what was written in the books, according to their deeds. ” (Revelation 20:12, NET)

“ For all who have sinned apart from the law will also perish apart from the law, and all who have sinned under the law will be judged by the law. ” (Romans 2:12, NET)

“ For the Son of Man will come with his angels in the glory of his Father, and then he will reward each person according to what he has done. ” (Matthew 16:27, NET)

It is a sin to deny the Holy Spirit, it is blaspheme. What these texts seem to say is that unbelievers will be judged by their sins. I believe it is becuase it was not applied to their account, because they did not believe.

If Christ made propitiation for all sin, including the sin of those who
do not believe, how can they be judged again for the sins Christ
already propitiated? This does not make sense.

It seems most people are confusing propitiation/expiation with justification.

A man can still be judged for his sins even in the universal view, because he has not been declared righteous.

Yes, they can not be taken together, Propitiation is what allows justification (declared innocent of guilt or declaired righteous)  for without propitiation there would never be justification.

But as DS said. In order to receive the result of propitiation and be justified,, you must have faith..

Of course. You receive justification by faith. You are not justified until you believe.

The point is that people who go to hell, go there for there sins. Jesus may have paid for the word's sins, but his atonement does not apply to you unless you receive it by faith.

This whole "Jesus paid for every sin but one" bit does not make sense. Jesus obtained eternal salvation. And it is applied to everyone who believes.
