8J. I. Packer's Keep in Step with the Spirit focuses on the person and ministry of the Holy Spirit. Now in its second edition, this book is not merely a theological study, but a rousing call to encourage believers to implement the Spirit's directives in their lives. Packer explains how to get the Spirit in focus and how to map the Spirit's path in life. He restates the Christ-centeredness of the Spirit's ministry, reaffirms the biblical call to holiness, and even-handily assesses the charismatic movement. Readers wanting to understand this movement, believers interested in the ministry of the Spirit, and fans of J. I. Packer's writings will appreciate this radical call to personal and corporate revival.
