Kevin DeYoung presents the Holy Spirit as our ultimate gift and outlines the Spirit’s active role in our lives. The Holy Spirit is perhaps the least understood, and least acknowledged, member of the Trinity, but his work in the gospel is indispensable. In this new booklet from the Gospel Coalition, Kevin DeYoung looks to Scripture to outline fundamental doctrine about the personhood and work of the Holy Spirit. DeYoung describes the Holy Spirit as our ultimate gift. Jesus promised his followers that a "helper" would be given to them. It is through this helper that we actively experience the power and presence of God. In this booklet DeYoung notes the activity of the Holy Spirit in our lives, including his role in conviction, conversion, glorification, and the imparting of spiritual gifts. The Holy Spirit offers a thoughtful explanation for point 9 of the Gospel Coalition's confessional statement. The Gospel Coalition is an evangelical renewal movement dedicated to a scripture-based reformation of ministry practices.
