Book excerpt: The disciples and early Christians faced doubt, opposition, and threats--just like many Christians do today. In Together with the World, Michael Wagenman shows how the book of Acts can help modern Christians respond to crisis and critique in our contemporary world. The book of Acts is about more than simply the beginning of church history. In Together for the World we find a group of disciples, empowered by the Holy Spirit, following God's call to spread the good news.
