In the first chapter of Acts, Luke introduces several important gospel perspectives that recur throughout the rest of the book. Principal among them is that the book of Acts is first and foremost a book about Jesus. He is the primary character of the book and the centre of all its events.
Acts portrays the continuing work and teachings of Jesus, following His ascension, in a way that no other book of the Bible does. Acts demonstrates that as the flowering movement spreads, Jesus Himself is at work. The Church is Jesus’ instrument to continue His work in the world.
In the opening chapter, Jesus promises His disciples the empowering presence of the Holy Spirit, commissions them to take the gospel to the “end of the earth”, ascends into heaven, and promises to return again.
