How do the christian concepts of heaven and hell differ from the Greeks idea of what?

Christian concepts of heaven and hell are based on the belief in eternal life and moral judgment, where heaven is a place of eternal communion with God for the righteous, and hell is a place of punishment for the wicked. In contrast, the ancient Greek idea of the afterlife, particularly in the realm of Hades, was less focused on morality and more about a shadowy existence where souls resided after death, with varying degrees of reward or punishment, such as the Elysian Fields for the virtuous and Tartarus for the wicked. While Christianity emphasizes a clear dichotomy based on moral choices, Greek beliefs were more about the inevitability of death and the continuity of existence in a less defined afterlife.
