Some issues in life are not capable of final resolution. Questions such as ‘What is the good life?’ and ‘How can we get good government?’ and ‘Whom can I trust?’ are not amenable to definitive answers in the same way as many mathematical and scientific questions. Rather, such fundamental questions of living recur afresh in every age. Part of the thesis of this chapter is that the role of the Old Testament in Christianity is, in essence, such an irresolvable issue. Christians ancient and modern have not found unanimity or finality in understanding and using the Old Testament – and this may be a sign not of failure but rather of the intrinsic variety of the challenges that the Old Testament poses for Christian faith. A collection of religious literature that is pre-Christian in origin, written over centuries and initially compiled by Jews (as Israel's Scriptures), and only subsequently appropriated by Christians (as the Old Testament), inherently poses intriguing, albeit enriching, questions to Christians.

Lack of definitive resolution therefore should in no way call into question the importance of wrestling with understanding the Old Testament within Christian faith. A. H. J. Gunneweg, for example, wrote

Thus, engagement in debates about the understanding and appropriation of the Old Testament – debates which in practice probably take place more in contexts of worship and everyday life than in formal academic contexts – is itself part of what constitutes Christian faith.
