“If we live by the Spirit, let us also keep in step with the Spirit.” —Galatians 5:25 Many Christians throughout the years have struggled to understand the person and work of the Holy Spirit. Seeing the potential for learning—as well as for confusion—theologian J. I. Packer wrote this comprehensive guide celebrating an often-misunderstood person of the Trinity. In Keep in Step with the Spirit, he explains how the Holy Spirit acted powerfully throughout creation and history, and continues to move in the lives of believers today, influencing our sanctification, spiritual gifts, and witness. Packer shares examples of the Spirit in the Old and New Testaments, and thoughtfully analyzes the strengths and weaknesses of charismatic theology. This updated, expanded edition includes an additional essay from Packer on Paul’s words in Romans, which emphasize the certainty of hope imparted to believers through the Holy Spirit.
