"The human heart desires joy. We all desire joy, every family, every people aspires to happiness. But what is the joy that the Christian is called to live out and bear witness to? It is the joy that comes from the closeness of God, from his presence in our life. From the moment Jesus entered into history, with his birth in Bethlehem, humanity received the seed of the Kingdom of God, like the soil receives the seed, the promise of a future harvest."
