Why Trust the Bible? - Paperback

Can You Really Trust the Bible?

It is the world’s most widely distributed book. It has shaped civilisations, transformed lives, and stood at the centre of the Christian faith for two thousand years. And yet the question pressing on millions of people — believers and sceptics alike — remains: Can we actually trust it?

Is the Bible historically reliable? Has it been corrupted over centuries of copying and translation? Did the church simply decide what belonged in it? And if it really is God’s Word — how would we even know?

Why Trust the Bible? by Greg Gilbert takes these questions head-on. Written with the same clarity, accessibility, and intellectual honesty that made What Is the Gospel? and Who Is Jesus? so widely used, this short book provides both the historical and theological arguments that have helped Christians across the centuries — and continue to help them today — to place their confidence in Scripture from Genesis to Revelation.

For the Doubter, the Seeker, and the Long-Time Believer

One of the great strengths of this book is the breadth of its intended audience. Gilbert writes for the non-Christian who finds the Bible’s claimed authority puzzling or unconvincing. He writes for the new believer who has embraced the faith but feels uncertain how to answer hard questions about Scripture. And he writes for the long-time Christian who has trusted the Bible for years but has never quite worked out why — and who struggles to articulate that trust when challenged.

In all three cases, Gilbert’s approach is the same: patient, honest, and genuinely engaging. He does not dismiss the hard questions. He works through them, one by one, with care.

Completing the Trilogy

Why Trust the Bible? is the natural third volume in Greg Gilbert’s accessible and widely-used trilogy of short 9Marks books for seekers and new believers:

• What Is the Gospel? — the heart of the Christian message
• Who Is Jesus? — the identity, claims, and significance of Christ
• Why Trust the Bible? — the reliability and authority of God’s Word

Together, these three volumes provide a complete, readable, and biblically grounded introduction to the foundational questions of the Christian faith. They work powerfully as a set for evangelism, enquirers’ groups, or new believers’ discipleship — and each stands alone as an equally useful standalone resource.
