When the New Testament describes what it means to be a Christian, it uses a phrase that is everywhere in Paul's letters but almost nowhere in our churches. Overwhelmingly, when the Bible wants to describe being a Christian, it says that we are in Christ. But what does it mean to be in Christ? And how does this important biblical idea help us understand what God has done for us through Jesus, and what it means to be a Christian? This short book by Rory Shiner sparkles with clarity, wit and biblical wisdom on this vital and much-neglected topic. This book is part of our Guidebooks for Life series. Like other titles in the series, it covers an important issue of the Christian life in an accessible and straightforward way.
