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 first and great commandment nonetheless. Even in the wilderness - especially in the wilderness - you shall love him.
The Shield was another of the Fear's names. According to Laughter, it means he shields the seed of Abraham the way a man starting a fire shields the flame. When Sarah was about to die childless, the Fear gave her a son. When Abraham was about to slaughter the son, the Fear gave him the ram. He is always shielding us like a guttering wick, Laughter said, because the fire he is trying to start with us is a fire that the whole world will live to warm its hands at. It is a fire in the dark that will light the whole world home.
If we are to believe he is really alive with all that that implies, then we have to believe without proof. And of course that is the only way it could be. If it could be somehow proved, then we would have no choice but to believe. We would lose our freedom not to believe. And in the very moment that we lost that freedom, we would cease to be human beings. Our love of God would have been forced upon us, and love that is forced is of course not love at all. Love must be freely given. Love must live in the freedom not to love; it must take risks. Love must be prepared to suffer even as Jesus on the Cross suffered, and part of that suffering is doubt.
They are prepared for a God who strikes hard bargains but not for a God who gives as much for an hour's work as for a day's. They are prepared for a mustard-seed kingdom of God no bigger than the eye of a newt but not for the great banyan it becomes with birds in its branches singing Mozart. They are prepared for the potluck supper at First Presbyterian but not for the marriage supper of the lamb..
