Yesterday we started the book of Acts.
One of the reasons we read the book of Luke and are now reading the book of Acts back to back is because Luke is both the author of the gospel of Luke and the book of Acts. Basically, Luke is the story of the life and work of Jesus and Acts is the story of the work of the Holy Spirit in the church.
Below are two video primers for Acts. The first is on Luke-Acts, showing us the connection between these books. The second helps give us a foundation on the book of Acts. Take a few minutes and watch them. They will be of help to you!
