William Law emphasizes that true Christian devotion extends beyond mere prayer, advocating for a life wholly dedicated to God in every aspect. He argues that devotion should permeate all actions, aligning them with God's will and glory, rather than being confined to specific times of prayer. Law critiques those who appear devout in church but live like the world outside, highlighting the absurdity of pious prayers without a corresponding holy life. He calls for Christians to embody their faith in daily actions, demonstrating humility, self-denial, and love for others as integral parts of their devotion. Ultimately, Law insists that a genuine Christian life must reflect the principles of devotion in all areas, not just during prayer.
