He has never left...

Hes everything, hes everywhere.

We just mistreated him every lifetime to the point that maybe some day he can rule his people again instead of these dark entities.

He said John the Baptist was Elijah...

He is every soul who wears his courage to guide them. Paramedics, emergency responders, musicians, doctors etc etc.

Maybe we just forgot how to see him and are now gaining eyes to see so we can finally be home with him again.
