Really good book, makes me want to teach through a "Why the Reformation Matters" class and use this as a primary text. Maybe I will. Trueman hits the nail on the head and challenges the reforming to embrace the heart of the Reformation. Covers and applies to the church from three main topics in this quick read: Jesus and his cross, the Scriptures read and preached, and assurance of salvation. Read it, and I'm guessing you'll want to keep reading the reformers.
