The Book of Acts records the history of the early church after the resurrection and ascension of Jesus Christ. Written by Luke, it follows the work of the Holy Spirit in empowering the apostles, especially Peter and Paul, to spread the gospel from Jerusalem to the ends of the Roman world. Acts highlights key events such as Pentecost, the conversion of Saul, missionary journeys, and the growth of Christian communities despite persecution. It serves as both a historical record and a guide for Christian mission, discipleship, and the unity of believers.
