Revival is the sovereign work of God to awaken his people with fresh intensity to the truth and glory of God, the ugliness of sin, the horror of hell, the preciousness of Christ’s atoning work, the wonder of salvation by grace through faith, the urgency of holiness and witness, and the sweetness of worship with God’s people.
—John Piper, A Godward Life, p. 111.
