Expository Exultation Over the Glories of God in His Word

What is preaching? Piper provides this alluring definition:

Christian preaching, as part of the corporate worship of Christ's church, is expository exultation over the glories of God in his word, designed to lure God's people from the fleeting pleasures of sin into the sacrificial path of obedient satisfaction in him.

—John Piper, God's Passion for His Glory: Living the Vision of Jonathan Edwards (Wheaton: Crossway, 1998), 39.
