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.
