The Bible's Book of the Acts of the Holy Spirit, commonly known as the "Book of Acts" or the "Acts of the Apostles," details the beginning and expansion of Christianity and its church. The fifth book in the Christian New Testament, it is also the second half of a two-part work written by Luke, a first century doctor and historian. Offering detailed analysis and commentary of each of the book's verses, author Donald C. Buck uses his years of research, ministry, and study to offer fresh insight into the early church and the working of the Holy Spirit in the world both then and now. Buck also addresses the book's primary areas of interpretation, including the title, the authorship of Luke, the date of writing, and the book's purpose, as well as Luke's status as an eyewitness, the sources he used, and his trustworthiness as a historian. Filled with rich insights and detailed research, is an essential addition to the library of anyone interested in how God's Holy Spirit continues to work in the twenty-first century.
