Therefore bread was created for the glory of Christ. Hunger and thirst were created for the glory of Christ. And fasting was created for the glory of Christ.
Which means that bread magnifies Christ in two ways: by being eaten with gratitude for his goodness, and by being forfeited out of hunger for God himself. When we eat, we taste the emblem of our heavenly food—the Bread of Life. And when we fast we say, “I love the Reality above the emblem.” In the heart of the saint both eating and fasting are worship. Both magnify Christ.
