What we believe shapes how we live, worship, and witness. We Confess is a three-volume series designed to help followers of Jesus know, love, and worship the Triune God more deeply. Rooted in the historic Christian faith and written with clarity and conviction, each volume explores core doctrines that form the heart of Christian belief. With biblical reflection, theological depth, and practical application, this series invites readers to confess their faith with understanding—so they may live it out with faithfulness in the church and in the world. The Spirit is God's empowering presence—at work in us and through us for the life of the world. God's Work in the World: The Spirit is the final volume in the We Confess series, focusing on the person and work of the Holy Spirit. It explores how the Spirit applies salvation, forms the church, equips believers for mission, and sustains hope for the renewal of all things. From new birth to new creation, this volume shows how the Spirit unites us to Christ, empowers our witness, and sends us into the world with gospel purpose. With theological clarity and practical depth, this book invites readers to live in step with the Spirit—until Christ returns and makes all things new.
