Praying without ceasing means: never losing contact with God, letting ourselves be constantly touched by him in the depths of our hearts and, in this way, being penetrated by his light. Only someone who actually knows God can lead others to God. Only someone who leads people to God leads them along the path of life.

The restless heart of which we spoke earlier, echoing Saint Augustine, is the heart that is ultimately satisfied with nothing less than God, and in this way becomes a loving heart. Our heart is restless for God and remains so, even if every effort is made today, by means of most effective anaesthetizing methods, to deliver people from this unrest. But not only are we restless for God: God’s heart is restless for us. God is waiting for us. He is looking for us. He knows no rest either, until he finds us. God’s heart is restless, and that is why he set out on the path towards us – to Bethlehem, to Calvary, from Jerusalem to Galilee and on to the very ends of the earth. God is restless for us, he looks out for people willing to “catch” his unrest, his passion for us, people who carry within them the searching of their own hearts and at the same time open themselves to be touched by God’s search for us. Dear friends, this was the task of the Apostles: to receive God’s unrest for man and then to bring God himself to man.

The wise men followed the star. Through the language of creation, they discovered the God of history. To be sure – the language of creation alone is not enough. Only God’s word, which we encounter in sacred Scripture, was able to mark out their path definitively. Creation and Scripture, reason and faith, must come together, so as to lead us forward to the living God. There has been much discussion over what kind of star it was that the wise men were following. Some suggest a planetary constellation, or a supernova, that is to say one of those stars that is initially quite weak, in which an inner explosion releases a brilliant light for a certain time, or a comet, etc. This debate we may leave to the experts. The great star, the true supernova that leads us on, is Christ himself. He is as it were the explosion of God’s love, which causes the great white light of his heart to shine upon the world. And we may add: the wise men from the East, who feature in today’s Gospel, like all the saints, have themselves gradually become constellations of God that mark out the path. In all these people, being touched by God’s word has, as it were, released an explosion of light, through which God’s radiance shines upon our world and shows us the path. The saints are stars of God, by whom we let ourselves be led to him for whom our whole being longs.
