Everything we know about Antony comes from a hagiography (a favorable biography of a saintly person) written shortly after his death by the famous theologian Athanasius. According to him, Antony saw the Christian's task as both simple and formidable: become a "lover of God" by resisting the Devil and yielding to Christ. Antony saw the world as a battlefield on which God's servants waged war against the Devil and his demons.
