The book, Divine Devotion, is a series of Christion literature. The first series is Holiness in Christ Jesus. It teaches us that all we need to know about holiness and why we should strive to be holy. In addition, as obedient children, do not be conformed to the former lusts which were yours in your ignorance, but like the Holy One who called you, be holy yourselves also in all your behavior; because it is written, "You shall be holy, for I am holy."
