Revelation 20: 15
15 And anyone not found written in the Book of Life was cast into the lake of fire.
To be cast into the Lake of fire and seperation from God is the ultimate Wrath of almighty God.
John 3:18 “He who believes in Him is not condemned; but
he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
To me this is the worst thing that could ever happen to man. Nothing compares to this!
