But what about those who choose not to believe in the reality of the spiritual war?
This is a no-brainer as far as I'm concerned.
People who choose not believe in the reality of the spiritual war choose not believe in the reality of the spiritual.
People who choose not believe in the reality of the spiritual, choose not believe in God.
People who choose not to believe in God also choose not to believe in Satan.
Unbelievers believe their unbelief has allowed them to transcend all spiritual considerations.
Unbelievers believe their despiritualization is liberty.
This is a delusion. Though their consciousness may be despiritualized, they are still spiritual beings, but they are spiritual beings who have forfeited the spiritual resources needed the resist the Satanic forces of objectification in the given world.
Put another way, unbelievers have surrendered all of their internal (spiritual) power and are completely at the mercy of external (material) power.
And what about those who think they have chosen to be on the side of God and Creation but are actually on the side against God and Creation?
Best leave that for another day.
