This chapter presents a mode of doing practical theology animated by Walter Brueggemann’s prophetic imagination. Drawing on Brueggemann’s description of the context within which prophetic imagination arises, I begin by outlining four pillars that frame the dynamic of criticising and energising by which practical theology in prophetic-imaginative mode is characterised. Second, I offer an assessment of this mode, giving attention to critical concerns typical of evangelicalism. After discussing my own starting points of imagination, this assessment develops four areas in which the prophetic-imaginative mode might contribute to practical theology: imagination in theology; attention to divine action; practical theology as ecclesial; and the place of power and affect.
