What Is Baptism — and Why Does It Matter?

Baptism is one of those subjects that every Christian encounters, yet many find surprisingly difficult to explain. What exactly is happening when someone is baptized? Who should receive it? Does it really have anything to do with church membership? And why do Christians seem to disagree about it so much?

In Understanding Baptism, Bobby Jamieson cuts through the confusion with clarity, warmth, and careful attention to what the Bible actually says. This short, accessible book shows that baptism is not a peripheral ritual or a mere formality — it is a glorious, gospel-saturated picture of a believer’s union with Jesus Christ in his death, burial, and resurrection. Jesus himself commands it. The church has always practised it. And every Christian deserves to understand it.

Whether you are preparing for your own baptism, helping someone else think through it, or simply wanting to understand this foundational practice of the Christian life, this book is written for you.
