The answer is: Luke

Acts 1:1 / Luke 1:3 - showing Acts to be a subsequent work of Luke.

When stepping into the remarkable world of the Book of Acts, it shines a light on the captivating achievements of the early followers of Jesus. Written by Luke, the same fellow responsible for the Gospel that bears his name, Acts serves as sort of a sequel, showcasing the waves of faith traveling through new lands.

One fascinating tidbit—to really appreciate this account, it helps to acknowledge that Luke was a physician. Unlike most of the other authors, he wasn’t among the original apostles, but he definitely brings a unique perspective to his writings. Through his detailed narratives, he contributes a well-researched account of life in the early church, filled with adventure, conflict, and unwavering faith. He shares both the stories of great Christian leaders, such as Peter and Paul, intertwining their journeys in a dynamic tapestry of unfolding events.

Moreover, Acts doesn’t shy away from the struggles of those early believers. Imagine the courage it took to spread their message amidst persecution and skepticism! Like echoes of the message of love and compassion found in the Gospels, Acts propels those ideas into action, emphasising community and unity. This is how believers took their faith from confinement to the broad horizons, testing their beliefs and shaping what it means to live an active faith in a diverse world. In short, Acts can genuinely be thought of as a thrilling chapter in an overarching saga of liberation and transformational hope.
