Stephen J. Hamilton attempts to create a portrait of born-again Christianity by providing a general introduction to the doctrine of regeneration, including its development in modernity, as well as short exegeses of relevant scriptural texts, followed by a close reading of four theologians Philipp Jakob Spener, Jonathan Edwards, Friedrich D.E. Schleiermacher, and Charles G. Finney who all associate the doctrine of regeneration with an experience of presence in the individual believer.In light of these analyses, he then traces a general theological structure of the born-again understanding of regeneration, including a catalogue of theological issues over which there is significant disagreement, in order to create a topography of born-again theologies. In the final section, he applies these results to contemporary conversion narratives of non-theologians. It is in such conversion narratives, the author argues, that theologians can discover an implicit, lived theology that reveals how doctrines are perceived and put into practice among Christians. Accordingly, this is to be understood as the result of the creative reciprocity between (often tacit) theological convictions and the experiences of the Christian life. The final chapter, as a coda to the entire work, offers some concluding reflections on the present cultural and political situation in the USA pertaining to born-again Christianity and argues against any oversimplifications of the relationship between born-again theologies, culture, and politics.
