Who can number adequately all the benefits of the desert and the advantages for virtue enjoyed by those who live there? Finding themselves placed in … - Eucherius of Lyon

I would say that the desert deserves to be called a temple of our God without walls. Since it is clear that God dwells in silence, we must believe that he loves the solitary expanses of the desert. ... Although God is present everywhere, and regards the whole world as his domain, we may believe that his preferred place is the solitudes of heaven and of the desert.

Scripture says that the Lord Jesus was accustomed to go into a desert place to pray. The desert may rightly be called a place of prayer, for God himself has approved it and taught by his example that it is appropriate for prayer. The prayer of a humble petitioner will more easily penetrate the clouds if it rises from the desert, because that solitary place gives it increased merit. The Lord Jesus, seeking that place for prayer, showed us where he prefers us to pray.

I am convinced that God, in foreknowledge of the future, prepared the desert for the saints to come. I believe he wanted some parts of the world to be rich in the fruits of agriculture and other parts, with drier climate, to abound with holy men. In this way the desert would bear fruit. When he ‘watered the hills from the heights above’, the valleys were filled with plentiful crops. And he planned to endow the sterile deserts with inhabitants, lest any land go to waste.
