In this New Studies in Biblical Theology volume, Andreas J. Köstenberger and Scott R. Swain provide a thorough biblical survey and theological treatment of the three persons of the Godhead in John's Gospel.

Bruce Ware provides an approachable examination of the doctrine of the Trinity. He discusses the relationship and roles of the Father, Son, and Holy Spirit and the practical implications of the Trinity for our lives.

Our six authors from four continents representing several branches of Evangelicalism are united in affirming the classical Christian understanding of God as Trinity as crucial for knowing God, understanding the world, and serving God honestly. Their essays lead up to a compilation of classical creeds regarding this foundational proclamation. Thomas K. Johnson: “The Trinity is a matter of knowing God in his complexity, totally different from us in our singularity yet radically similar in having personality in his image, then letting this knowledge of God become the pattern of a renewed Christian mind.” Brian Edgar: “This presentation of the consummate dimensions of the Trinity . . . tells us that the life of God as Trinity is something in which we participate rather than something to be intellectually comprehended.” J. Scott Horrell: “The suggestion, humbly submitted, is especially for a missional Trinitarian worldview—not missional as from one culture to another, but missional as each body of believers seeks to engage and express Trinitarian faith within their own culture.” William P. Atkinson: “As the Father’s kenotic ‘leadership’ of the Trinity thereby exalts the Son and the Spirit, so too we can expect that the sort of servant-leadership that answers Jesus’ high-priestly prayer will lift those who are being led.” Pavel Hošek: “The Enlightenment reductionist rationalism in theology is going through a serious crisis, and the relativistic postmodern alternatives do not provide any firm epistemological basis for responsible theological thinking. I suggest that the trinitarian intellectual framework which Comenius and Lewis tried to develop offers a promising and inspiring way forward for Christian theologians faithful to the orthodox teachings of the church who are struggling with the intellectual challenges of contemporary culture.” Tersur Aben: “The Trinity is the heart of God’s self-disclosure to and involvement with humans on earth. . . . The mission of the church is thus to proclaim the gospel of salvation and the restoration of humans back to God, which the Son accomplished on Calvary and the Holy Spirit applies to believers on Pentecost.”

For the Spirit, being somewhat forgotten is an occupational hazard. The Holy Spirit is so actively involved in our lives that we can take his presence for granted. As they say, familiarity breeds contempt. Just as we take breathing for granted, we can take the Holy Spirit for granted simply because we constantly depend on him. Like the cane that soon feels like an extension of the blind man’s own body, we too easily begin to think of the Holy Spirit as an extension of ourselves. Yet the Spirit is at the center of the action in the divine drama from Genesis 1:2 all the way to Revelation 22:17. The Spirit’s work is as essential as the Father’s and the Son’s, yet the Spirit’s work is always directed to the person and work of Christ. In fact, the efficacy of the Holy Spirit’s mission is measured by the extent to which we are focused on Christ. The Holy Spirit is the person of the Trinity who brings the work of the Father, in the Son, to completion. In everything that the Triune God performs, this perfecting work is characteristic of the Spirit. In Rediscovering the Holy Spirit, author, pastor, and theologian Mike Horton introduces readers to the neglected person of the Holy Spirit, showing that the work of God’s Spirit is far more ordinary and common than we realize. Horton argues that we need to take a step back every now and again to focus on the Spirit himself—his person and work—in order to recognize him as someone other than Jesus or ourselves, much less something in creation. Through this contemplation we can gain a fresh dependence on the Holy Spirit in every area of our lives.

What if the Trinity we've been taught is not the Trinity of the Bible? In this groundbreaking book, Matthew Barrett reveals a shocking discovery: we have manipulated the Trinity, recreating the Father, Son, and Holy Spirit in our own image. With clarity and creativity, Barrett mines the Scriptures as well as the creeds and confessions of the faith to help you rediscover the beauty, simplicity, and majesty of our Triune God. You will be surprised to learn that what you believe about the Trinity has untold consequences for salvation and the Christian life. To truly know God, you must meet the One who is simply Trinity.

Communion with God, or in full, "Of communion with God the Father, Son, and Holy Ghost each person distinctly, in love, grace, and consolation; or, the saints' fellowship with the Father, Son, and Holy Ghost unfolded," is John Owen's finest devotional treatise. This work expounds "the most glorious truth that believers may have distinct communion with the three persons Father, Son, and Spirit," and being addressed to the "Christian reader" is simpler than much of Owen's theology. (Unabridged. Includes all footnotes.)

In this brief and winsome book, Michael Reeves presents an introduction to the Christian faith that is rooted in the triune God. He takes cues from preachers and teachers down through the ages, setting key doctrines of creation, the person and work of Christ, and life in the Spirit into a simple framework of the Christian life.
