"Preparing for Marriage: Help for Christian Couples" is a book by John Piper, published by Desiring God, which aims to help Christian couples in their preparations for marriage. The book is divided into six chapters that cover topics such as: the engagement period, wedding planning, the complementary dynamics between husband and wife, sexual relations in marriage, the importance of protecting marriage in a world that attacks it, and the ultimate goal of marriage: to be lived for the glory of God.

Each chapter is developed based on biblical passages and theological reflections, with the aim of offering a Christian perspective on married life. The work emphasizes the need to prioritize faith in God in all spheres of life, including marriage, and highlights the importance of building a solid relationship, based on biblical principles of love, respect, leadership, and submission.

In addition to the main chapters, the book includes two appendices. The first provides an extensive list of questions for couples to discuss important issues regarding faith, values, lifestyle, relationships with friends, family, children, and finances. The second appendix addresses the topic of hospitality, addressing the importance of welcoming others, especially brothers and sisters in Christ, as a way of demonstrating God’s love and being a witness to the world.

In short, the book is a practical and theological guide for Christian couples seeking to build a solid and lasting marriage, founded on biblical principles and oriented to the glory of God.
