The God on whom we rely knows what suffering is all about, not merely in the way that God knows everything, but by experience. In the darkest night of the soul Christians have something to hold onto that Job never knew. We know Christ crucified. Christians have learned that when there seems to be no other evidence of God’s love, they cannot escape the cross. “He who did not spare his own Son, but gave him up for us all – how will he not also, along with him, graciously give us all things?”(Rom. 8:32) … When we suffer, there will sometimes be mystery. Will there also be faith? Yes, if our attention is focused more on the cross, and on the God of the cross, than on the suffering itself.
