CLose, it's not to deny the Holy Spirit but to, well here:<quoted text>
I'm not wrong. According to the Bible, the only unforgivable sin is to deny the Holy Spirit. Anything else is fine.
So let's look at it from your perspective: how much sin is enough to overcome the sacrifice of Jesus?
Mark 3:29 But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation:
The Holy Ghost (Spirit) IS God.
Matthew 12:32 And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.
Hitler did a great deal of "speaketh against the Holy Ghost" during his life.
No amount of good works and the keeping of Gods laws can be sufficient to atone for sin. All their thoughts, words and actions will be judged against Gods perfect standard and found wanting. There will be no reward for them, only eternal condemnation and punishment.
