On the books of Luke and Acts:
“…the biblical promises and allusions throughout the first book create a foreshadowing of things to come. Or…the allusions produce a suspension that awaits resolution. As the associations between Jesus and various Old Testament precursors accumulate throughout the Gospel, we find ourselves wondering ever more urgently when and how he (Christ) will assume the role promised in the story’s beginning and whether his finally disclosed identity will integrate and fulfill the wide range of typological roles suggested by the many tantalizing intertextual motifs sounded throughout the Gospel. In short, Luke’s gospel story sets up narrative expectations that are satisfied or brought to closure only in Acts. The Gospel – like Israel’s Scripture – points beyond itself.”
