Reese Watt has researched the biblical doctrine of hell for nearly thirty years. Here is a graphical representation of what he has found.
- eternal torment: the “traditional” idea of eternal conscious torment in a blazing, unquenchable, torturous fire
- annihilation: God puts the wicked out of their misery, annihilating them so that they cease to exist
- universal repentance: also known as “universalism,” eventually everyone repents and gets out of hell
- neutral: texts here could endorse any of the previous three views
