Real doom is the experience of one who cannot escape hell. It is only experienced by people in hell and by those who have rejected repeated warnings by God to choose to stop sinning. How many warnings only God knows. Any person who has rejected repeated warnings by God to choose to stop sinning, who then chooses to stop sinning, has a chance of being given an opportunity to obtain the promise from God that they will go to heaven when they die. Any person who has not rejected repeated warnings by God to choose to stop sinning, who then chooses to stop sinning, will be given an opportunity to obtain the promise from God that they will go to heaven when they die. In the Bible in Acts 10, a man named “Cornelius” took advantage of an opportunity to obtain the promise from God that he would go to heaven when he died.
