Book excerpt: The Bible reveals we are in a battle—a spiritual war waged on earth and in heavenly places—for our very souls. We have a real enemy of our faith who wants to take away our peace, joy, and happiness. It is his desire to destroy lives. It is God’s desire to restore them. In Guerilla Christianity, author James Costello demonstrates, through sound life principles and scripture passages, there is a way to battle the enemy of our faith and to live a faith-filled life. He weaves personal accounts of loss and spiritual battle with tales of bravery and faith. Offering inspiration to others, he provides examples of God’s spiritual weapons that were used to overcome extreme circumstances. James communicates that God does not want you—his child—to live a defeated, meaningless existence. He wants you to walk in the power of his might, to have a sense of purpose and direction.
