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 , 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.
