"This is, at the end of the day, the ultimate test of our knowledge of God. Is it robust enough that, when faced with excruciating adversity, it may prompt us to lash out with hard questions, but will never permit us to turn away form God?
But perhaps it is better to put the matter the other way round: the God who put Job through this wringer is also the God of whom it is said that, with respect to his own people, "he will not let (them) be tempted beyond what (they) can bear. But when (they) are tempted, he will also provide a way out so that (they) can endure it" (1 Cor. 10:13). God could not trust me with as much suffering as Job endured; I could not take it. But we must not think that there was any doubt in God's mind as to whether he would win his wager with Satan over Job!
When we suffer, there will sometimes be mystery. Will there also be faith?"
