I don't see how this relates anything to Christianity??
Satan does not have "servents of light"
God is light, and is the light of this dark world.
Psalm 43:3
Send forth your light and your truth,
let them guide me;
let them bring me to your holy mountain,
to the place where you dwell.
Isaiah 5:20
Destruction is certain for those who say that evil is good and good is evil; that dark is light and light is dark; that bitter is sweet and sweet is bitter.
Matthew 5:13-14
"You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled by men.
"You are the light of the world. A city on a hill cannot be hidden.
