Called to Serve: Living the Christian Faith is a Partial Book.
As a Partial Book, there is much to be added, and revised before it is complete. However, the draft does have about 50,000 words and 250 pages, so there should be enough to stimulate your thinking about what it means to be a Christian and what God requires of you.
Note: The book is setup in pdf, with a page size of 5″ by 8″ so you will need an app that can display pdf (Portable Document Format, an Adobe Acrobat format).
