The best news of the Christian gospel is that the supremely glorious Creator of the universe has acted in Jesus Christ's death and resurrection to remove every obstacle between us and himself so that we may find everlasting joy in seeing and savoring his infinite beauty.
John PiperThe purpose of the Lord's Supper is to receive from Christ the nourishment and strength and hope and joy that come from feasting our souls on all that He purchased for us on the cross, especially His own fellowship.
John PiperTherefore 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.
