Lesslie Newbigin's development of a fresh paradigm of missionary theology and cultural engagement has solidified his reputation as not just one of the most important missionary theologians of the twentieth century, but as continually relevant in the twenty-first. Paul Weston focusses on how the engagement with Michael Polanyi's understanding of 'personal knowledge' illuminates Newbigin's work, and contributes to its ongoing significance. Interlinking themes of 'Revelation', 'Knowing' and 'Story' and tracing through Newbigin's engagements with modernity and post-modernity, Weston suggests how the 'logic' of Newbigin's approach continues to provide insight to mission theologians and practitioners. It is Weston's conviction that Humble Confidence presents Newbigin's thinking in a way that can serve the continuing mission of the church.
