adversity does benefit

"If... we feel in these days that our experience is rough and humiliating, it simply presents an analogy to that portion of Israel's history which is, in a special sense, offered to us as an example and a warning; and if we feel that the adversity we have to endure cannot in any way benefit us, it suggests a terrible alternative, that instead of being numbered among the faithful to be purified, we are joining the ranks of the rebels to be purged out."
