The Book of Acts, often referred to simply as Acts, is a vital part of the New Testament that chronicles the early church's history and the spread of the Gospel after the ascension of Jesus Christ. Written by Luke, the same author of the Gospel of Luke, Acts serves as a sequel to his earlier work, providing a detailed account of the apostles' ministry, the establishment of the church, and the missionary journeys of Paul.
Acts is set in the first century, primarily in the regions of Jerusalem, Judea, Samaria, and the broader Roman Empire. The narrative begins in Jerusalem, where the early disciples receive the Holy Spirit at Pentecost, and it follows the expansion of the church through the efforts of key figures like Peter and Paul. The book highlights the challenges and triumphs faced by the early Christians as they spread the message of Jesus in a diverse and often hostile environment.
