Readers of the New Testament have long observed that "Luke" and "Acts" contain numerous scenes in which characters praise God. This study offers the first comprehensive analysis of this important narrative motif. Featuring a close reading of "Luke-Acts", it draws insights from ancient Jewish and Greco-Roman views about praise of deity, and it compares praise in "Luke" with praise in two other ancient narratives: Tobit and Joseph and Aseneth. Attention to praise of God sheds light on Luke as historiographer and on his treatment of revelation, healing, conversion, and eschatology.
