From Pope Benedict XVI's homily opening the Year of Faith today:
"Recent decades have seen the advance of a spiritual “desertification”. In the Council’s time it was already possible from a few tragic pages of history to know what a life or a world without God looked like, but now we see it every day around us. This void has spread. But it is in starting from the experience of this desert, from this void, that we can again discover the joy of believing, its vital importance for us, men and women. In the desert we rediscover the value of what is essential for living; thus in today’s world there are innumerable signs, often expressed implicitly or negatively, of the thirst for God, for the ultimate meaning of life. And in the desert people of faith are needed who, with their own lives, point out the way to the Promised Land and keep hope alive. Living faith opens the heart to the grace of God which frees us from pessimism. Today, more than ever, evangelizing means witnessing to the new life, transformed by God, and thus showing the path."
