Our appetites control much of what we do each day—whether it is the cravings of our stomachs, the desire for possessions or power, or the longings of our spirits for God. But for the Christian, the hunger for anything apart from God is ultimately detrimental to spiritual health and enduring joy. In this classic meditation on fasting, John Piper helps Christians apply the Bible's teaching on this long-standing spiritual discipline, highlighting the profound contentment that comes from delighting in God above all else. Piper helps readers put to death self-indulgence by directing them to the all-satisfying, sin-conquering glory of Christ. This volume is now redesigned with a new cover and a foreword by New York Times best-selling authors David Platt and Francis Chan.
