Biblical Theology - How the Church Faithfully Teaches the Gospel - Hardback

Every Week, Churches Around the World Read the Bible and Miss the Point.

It sounds alarming. But it is true — and it is more common than most Christians realise. A church can be Bible-reading, Bible-quoting, and Bible-teaching, and still miss the main message of Scripture week after week. And when that happens, false gospels quietly take root — moralism, self-help, prosperity, or a Christianity emptied of Christ — all dressed in the language of the Bible.

One of the most important safeguards against this danger, Nick Roark and Robert Cline argue, is an understanding of biblical theology.

In Biblical Theology, Roark and Cline make a compelling and accessible case for why churches must learn to read the Bible in light of its main message — the grand, unified story of God’s redemptive purposes culminating in Jesus Christ. Beginning with a clear framework for understanding the storyline of Scripture, and then offering practical principles for prioritising this message in church teaching, this short book equips churches to guard the truth of the gospel — not by adding more programmes or more rules, but by reading the Bible the way it was meant to be read.

This is a book for every pastor, teacher, and church member who wants to handle God’s Word faithfully — and ensure that what is proclaimed from their pulpit and taught in their small groups is genuinely the gospel of Jesus Christ.

What This Book Covers

Nick Roark and Robert Cline work through the foundations and practice of biblical theology for the local church:

• What biblical theology is — A clear, accessible definition of biblical theology and why it is distinct from systematic theology and other approaches to Scripture
• Why churches miss the main point — An honest account of how well-intentioned Bible teaching can still fail to proclaim the gospel — and what goes wrong
• The storyline of the Bible — A practical framework for understanding Scripture as a unified, coherent narrative moving from creation to new creation through the redemptive work of Christ
• Jesus Christ as the fulfilment of Scripture — How the entire Bible — law, history, poetry, prophecy, and epistle — finds its meaning and unity in Jesus
• Principles for gospel-centred teaching — Practical guidance for pastors and teachers on how to prioritise the gospel message in every sermon, lesson, and Bible study
• Guarding the truth in the local church — How a congregation shaped by biblical theology is better equipped to recognise and resist false teaching
• Biblical theology and church health — How reading the Bible rightly is foundational to everything else that makes a church healthy and gospel-centred
