The reason for the Spiritual war here, is many, but the biggest attacks are on keeping Humans from Spiritually Awakening because once awakened, the Human can command Gods power thru themselves & stop evil ones but evil doesn't want anyone knowing that! So evil creates fears.

Evils create fears, distractions, dis-informations anything & everything to keep humans in fear & completely distracted from finding God & understanding how God Created us IN HIS IMAGE aka: Spiritual Power.
