"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."
-From the Homily of Benedict XVI opening the Year of Faith.
