What does the Bible say about hell and the lake of fire?

The Bible makes a clear distinction between the concepts of hell and the lake of fire. Hell, referred to in the Old Testament as Sheol, signifies the grave or the abode of the dead. In the New Testament, the term Hades is similarly used to denote the place of the dead. However, the lake of fire, mentioned in Revelation, represents a different reality, one that signifies eternal punishment and destruction. It is a place prepared for the ultimate enemies of God, including Satan, death, and all whose names are not in the book of life. Understanding this distinction is crucial for grasping the full biblical teaching on eschatology and divine judgment.
