The spiritual warfare should be fought and won only by the spiritual ways.
To fight it with flesh and blood is guaranteed to be defeated.
See how America is defeated so miserably in Iraq and Afghanistan.
Burning Koran is the most ignorant way of fighting the spritual warfare with flesh and blood.
It's guaranteed to be trapped in the wiles of the devil, and the violent upheaval will be erupted by the enemy all over the world.
"For we wrestle not against flesh and blood, but against principalities, against powers,
against the rulers of the darkness of this world, against spiritual wickedness in high places."
