Do you believe that hell exists.
There are many people today who dislike any mention of the judgement of God. Perhaps they do not really believe that hell exists. Or perhaps they worry that they might frighten someone.
The author of Hebrews clearly did not agree with any opinions like those ones. He believed that he had a duty to warn people. Everyone will have to stand in front of God when he is their judge. There will be a punishment for sin (evil deeds). See Revelation 20:11-15.
