Jesus, before beginning His public ministry, withdrew to the desert for 40 days. Fasting, "He nourished Himself on the word of God, which He used as a weapon to defeat the devil," the Pope said.

Pope Benedict said experience of God's grace and of temptation is not unique to modern Catholics or to the Church.

During their 40 years in the desert, the people of Israel were guided by God, fed with manna and given water from a rock, but they also were tired, complaining and tempted to return to idol worship, the Pope said. And, spending 40 days in the desert before beginning His public ministry, Jesus experienced the closeness of God, but also faced the devil's temptations of "power, success and dominion."

"This ambivalent situation also describes the condition of the Church journeying through the desert of the world and history. In this desert, we believers certainly have the opportunity of having a profound experience of God, who strengthens our spirit, confirms our faith, nourishes our hope and animates our charity," the Pope said.

However, he said, "the desert is also the negative aspect of the reality that surrounds us: the aridity, the poverty of words and values, the secularism and materialism" that attempt to convince people that God does not exist.

Still, "the desert time can be transformed into a time of grace" because God's love is more powerful than the temptations of the world, the Pope said.
