Marriage by Paul David Tripp is an updated and repackaged version of his previous book What Did You Expect? In the new version, the title and cover have changed and there are two new chapters. Tripp says in the Preface to the 2021 edition that the older title seemed to communicate that the book was about “misguided or failed marriage expectations” when in reality the book is actually about “six marriage commitments that result from looking at marriage through the lens of the gospel of Jesus Christ.” The new edition intends to bring those commitments to the forefront. After reading this book, I think this was a great choice and a helpful rebrand.
