âOne of the features of the Book of Revelation is the way in which the images suggest that God is absent, but in fact is a present reality in life. In a world which seems bereft of God, John is allowed to see the reality. A door is opened in heaven and John sees God enthroned in glory...Even if another lord appears to rule the world at present, such a rule can only be temporary. The king of kings and Lord of lords is really ruler of the universe...â â âRevelationâ by Christopher Rowland. In the Catholic Church, we have four weeks to prepare ourselves spiritually for Christmas, a time we know as Advent. This Advent poses each of us the question: âWill I celebrate Christmas with gratitude, or with resentment that it is so different from every other Christmas I have known?â
