For decades, Third Millennium Ministries has been working to make a high-quality, orthodox theological education possible for anyone. Its Master's-level course materials are written in accessible language, vetted by Evangelical scholars, and used by seminaries, Bible colleges, churches, and mission organizations around the world. Now this established curricula is available in book form—an ideal resource for any student of theology, formal or informal. Practically speaking, the Holy Spirit is the person of the Trinity who is most involved in our daily lives. Yet study of the Holy Spirit, pneumatology, is often neglected despite his importance. The Nature and Work of the Holy Spirit shows how the doctrine of the Holy Spirit's distinct personhood developed historically, exploring his presence in the Old and New Testament. Readers will come to understand the Spirit's dynamic work in the world, in the church, and in believers.
