Acts was written by Luke the physician, the same author as the Gospel of Luke (Acts 1:1). Both books are addressed to Theophilus. Luke's participation in some events is evident through the 'we' passages (Acts 16:10-17, 20:5-15, 21:1-18, 27:1-28:16). The book was likely written around 62-80 AD.

Acts contains 28 chapters covering approximately 30 years (AD 30-62) of church history — from Jesus' ascension and the coming of the Holy Spirit at Pentecost, through the expansion of the church from Jerusalem to Rome, primarily following the ministries of Peter (chapters 1-12) and Paul (chapters 13-28).

The main theme of Acts is the unstoppable spread of the gospel through the power of the Holy Spirit. Jesus promised, 'you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth' (1:8). Acts narrates the precise fulfillment of this commission.

Key events include: the ascension of Jesus (chapter 1), Pentecost and the outpouring of the Holy Spirit (chapter 2), the martyrdom of Stephen (chapter 7), the conversion of Saul/Paul on the Damascus Road (chapter 9), Peter's vision and the inclusion of Gentiles (chapter 10), the Jerusalem Council (chapter 15), Paul's three missionary journeys (chapters 13-20), Paul's arrest and trials (chapters 21-26), and the shipwreck and arrival in Rome (chapters 27-28).

Acts is the indispensable bridge between the Gospels and the Epistles. Without Acts, we would not understand how the church was born, how Gentiles were included, or the context behind Paul's letters. The Jerusalem Council (chapter 15) established that salvation is by grace through faith, not by Law — a decision that shaped Christianity's identity as a universal faith distinct from Judaism.
