Saul was a violent persecutor of the early Christians until Jesus struck him down and converted him to Christianity. He became Paul, the most influential of all the apostles. In fact, he wrote about half the books in the New Testament. His letter to the Ephesians 2:8 is the basis of this book. 'For it is by grace that you have been saved...' This is one of the cornerstones of the Christian faith as you shall read in this book.
