This monograph explores the joy theme in Luke- Acts as it relates to the dynamics of rhetoric, narrative and emotion. The Gospel of Luke has been called the gospel of joy , and the joy theme has also been recognised in Acts. This theme, though, has received relatively little attention in NT scholarship. Joy in Luke-Acts examines the joy theme from a socio-rhetorical vantage point, showing that the joy theme empowers the Lukan rhetoric of reversal. The theme is a primary method in which the narrator seeks to persuade the reader to enter into the values and beliefs that characterise the 'upside-down' world in which YHWH has visited his people in Jesus.
