S03 E01 - The Book of Acts - Prelude to the Epistles

Why Luke broke it into two parts, gospel and Acts. What it shows us of discipleship and Jesus being alive in the world. Would the epistles have made any sense without this book? Luke's second book could be called the Acts of Jesus or the Acts of Jesus and the Spirit. It is the only account that we have of what happens after Jesus' resurrection before we get into the second century non-biblical Christian writings talking about the church.
