This is one thing, therefore I said it - This may mean, “it is all the same thing. It makes no difference whether a man be righteous or wicked. God treats them substantially alike; he has one and the same rule on the subject. Nothing can be argued certainly about the character of a man from the divine dealings with him here.” This was the point in dispute, this the position that Job maintained - that God did not deal with people here in strict accordance with their character, but that the righteous and the wicked in this world were afflicted alike.
He destroyeth the perfect and the wicked - He makes no distinction among them. That Job was right in this his main position there can be no doubt; and the wonder is, that his friends did not all see it. But it required a long time in the course of events, and much observation and discussion, before this important point was made clear. With our full views of the state of retribution in the future world, we can have no doubt on the subject. Heavy and sudden judgments do not necessarily prove that they who are cut off are especially guilty, and long prosperity is no evidence that a man is holy. Calamity, by fire and flood, on a steamboat, or in the pestilence, does not demonstrate the unusual and eminent wickedness of those who suffer (compare Luke 13:1-5), nor should those who escape from such calamities infer that of necessity they are the objects of the divine favor.
