Rediscovered Joy by Tim Chester and published by IVP Books.
This book looks at the dynamic power of the Reformation in the book of Galatians. The title, Rediscovered Joy, derives from Galatians 4:15 (NLT). The Galatians had lost the joy of God's blessing because they had departed from the truths of the gospel. The Reformation - and the book - is an invitation to rediscover the joy of the gospel. Despite the common claim that the Reformation is either out-dated or divisive, its rediscovery of the apostolic message was a rediscovery of joy - a message that is as relevant today as it was 500 years ago and 2,000 years ago.
