The book of Acts is the only account we have of how Christianity spread and multiplied during the thirty years following the death and resurrection of Jesus. In the words of Michael Green - "The book contains a tapestry of themes: the church, the ministry, the apostolic preaching, the Spirit, the charismats, church planting, Christian lifestyle, sacrifice, prayer, social concern, and many more. The Acts has much to say to our half-hearted and cold-blooded Christianity in the Western World."
