Trying to get a better understanding and how the bible use these terms. What brought me to this discussion is when Hell is casted into the Lake of Fire I assume the 'Second Death' is refering to an spiritual death.
So for instance when scripture speaks of there would be no more death it would imply to those that have their names written down in the book of Life.
So if Hell which I understand to mean Grave and Death which I understand to mean a spiritual death according to Revelation 21:4. How then are these casted into the Lake of Fire? So what is this really saying?
