The Acts of the Apostles explores the story of the early church, from its inception in Jerusalem to its continued existence in the Roman Empire. The early church firmly believed that it was not a new religion, but the realization and fulfillment of Judaism. However, as the church lived out its mission as the fulfillment of its own religious heritage, it had to learn to reach beyond the comfortable boundaries of its own Jewish traditions. Central to the fulfillment of the hopes of Scripture was the incorporation of all persons, Jews and non-Jews, into the people of God. This commentary explores this important broadening of the mission of God and brings lessons for modern Christians to continue the expansion through obedience.
