"God has appointed preaching in worship as one great means of accomplishing his ultimate goal in the world." —John Piper John Piper makes a compelling claim in these pages about the purpose of preaching: it is intended not merely as an explanation of the text but also as a means of awakening worship by being worship in and of itself. Christian preaching is a God-appointed miracle aiming to awaken the supernatural seeing, savoring, and showing of the glory of Christ. Distilling over forty years of experience in preaching and teaching, Piper shows preachers how and what to communicate from God's Word, so that God's purpose on earth will advance through Biblesaturated, Christ-exalting, God-centered preaching—in other words,  expository exultation.
