"Hear, O Israel! Only more often than not we hear nothing because we live in a wilderness where more often than not there is nothing of God to hear. And of course it was in just such a wilderness that the great words of Moses were trumpeted forth in the first place, and the people who first heard them were in the wilderness with him, as wandering and lost as we are, with nothing to keep them going but the hope of a Promised Land, which much of the time seemed a promise so remote and improbable that even the bondage they had left behind them in Egypt looked hopeful by comparison. To be commanded to love God at all, let alone in the wilderness, is like being commanded to be well when we are sick, to sing for joy when we are dying of thirst, to run when our legs are broken. But this is the great and first commandment nonetheless. Even in the wilderness—especially in the wilderness—you shall love him."
