Who is the God of Death and GeiHinnom? Who Sits on the Fourth Spirit?

Who do you serve? Who is your king? Who has authority over you? Who decides when you die? Who has power to keep you dead? Whom do you fear?

If you are fearful you go there...Fear whoever has the power.

Rev 21:8
But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone:

Mat 10:28
And you should not be afraid of those killing the body but not being able to kill the soul. Indeed rather you should fear the One being able to destroy both soul and body in Gehenna.
