Signed, Sealed, Delivered

Signed, Sealed, Delivered: An Introduction to Covenant Theology offers an accessible overview of Reformed covenant theology, guiding readers through the biblical covenants that unite Scripture from Genesis to Revelation.

Dr. J.V. Fesko presents the three major covenants of the Reformed theological tradition: the covenant of redemption, the eternal agreement among Father, Son, and Holy Spirit; the covenant of works, established with Adam in the garden of Eden; and the covenant of grace, through which God saves His people by the work of Christ. Written for a broad church audience, the book traces how these covenants relate to one another and how they shape the reading of both the Old and New Testaments.

Fesko also addresses covenant signs—including circumcision, baptism, and the Lord’s Supper—and explores the relationship between God’s covenants and the life of the church. Each chapter includes review questions suited for personal or small-group study. Drawing on the historical development of covenant theology from the Reformation era and the Reformed confessions, this book serves as a concise primer that directs readers first to Scripture itself, with an appendix recommending further reading for those who wish to study the doctrine in greater depth.
