" What God is doing may be mystery, but who God is is not. So faith can remain itself and retain its integrity by suspending judgment. Jesus underwrites such faith when he promises, “I am the light of the world. No follower of mine shall wander in the dark.”9 He does not say we will never walk in the dark, but that we do not wander in the dark or have a way of life at home in darkness. To anyone not knowing the anguish of such a situation, the distinction may sound trivial—the darkness appears as dark and the dilemma as agonizing. But neither is ultimate, for the outcome lies with God. "
