The saints need to hear of the grace and mercy of God.
The World needs to hear of the wrath and judgment to come.
WE need to hear of the judgment and wrath to come to remind us that their very souls are at stake!
The fear of God, Hell is a place of eternal torment, The Love of God that made an escape, they will go there if they chose to.
A good God will not send them there, but A Good God allows and honors their choice.
