This book expands on scholarly arguments that the Gospel of Luke and Acts of the Apostles was originally intended as a single, unified work. It offers fresh insights by addressing overlooked perspectives and further exploring the literary, theological, and historical connections between the two volumes. Central to this study is the argument that the ascension narratives at the end of Luke and the beginning of Acts form a chiastic structure uniting and conjoining both volumes. Rather than redefining Luke-Acts as First and Second Luke, this study affirms their distinct literary genres: Luke's Gospel rightly belongs among the canonical Gospels, and Acts bridges the Gospels with the Epistles acting similar to a historical narrative. It does not seek to alter their canonical separation but asserts that Luke deliberately composed them as a continuous, interdependent account. By examining how this pivotal event structures the text, it provides compelling evidence of Luke's intentional design, demonstrating that the ascension is the hinge that seamlessly connects both volumes.
