“Packer’s book Keep in Step with the Spirit is polemically irenic. Seeking to promote peace in the church, Packer also desired purity. In this book, he offers an argument against certain opinions on the Spirit with a greater goal in mind: the peace of God’s people as they share a unified understanding of the Holy Spirit’s work. If his irenicism is the end, his polemics are the means. This is the hallmark of classically Reformed treatments on key theological doctrines, and I am thrilled to see this book republished by Crossway.”—Mark Jones, Senior Pastor, Faith Reformed Presbyterian Church (PCA), Vancouver, British Columbia“Typically biblical and balanced, the late J. I. Packer gives us a Christian’s field guide to life with the Holy Spirit. In an age marked by confusion and deception, this book helps point us clearly to the Bible’s truth about the Christian life.”—Mark Dever, Pastor, Capitol Hill Baptist Church, Washington, DC“When we face a debated theological topic, we need a guide who has no ax to grind, who is fair, honest, reasonable and—above all—carefully biblical. We Christians do debate the ministries of the Holy Spirit. But we have a reliable guide in J. I. Packer and Keep in Step with the Spirit. Reading this book, we feel understood, respected, instructed, and more open to the true powers of the blessed Spirit of God.”—Ray Ortlund, Pastor to Pastors, Immanuel Church, Nashville, Tennessee
