By almost any measure, a bold and confident use of the Bible is a hallmark of Christianity. Underlying such use are a number of assumptions about the origin, nature and form of the biblical literature, concerning its authority, diversity and message. However, a lack of confidence in the clarity or perspicuity of Scripture is apparent in Western Christianity. Despite recent, sophisticated analyses, the doctrine is ignored or derided by many. While there is a contemporary feel to these responses, the debate itself is not new. In this New Studies in Biblical Theology volume, Mark Thompson surveys past and present objections to the clarity of Scripture; expounds the living God as the Guarantor of his accessible, written Word; engages with the hermeneutical challenges and restates the doctrine for today. Addressing key issues in biblical theology, the works comprising New Studies in Biblical Theology are creative attempts to help Christians better understand their Bibles. The NSBT series is edited by D. A. Carson, aiming to simultaneously instruct and to edify, to interact with current scholarship and to point the way ahead.
