"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."
