Why dost thou strive against him? - By refusing to submit to him, and by calling in question his wisdom and goodness.
For he giveth not account of any of his matters - Margin, as in Hebrew “answereth not.” The idea is, that it is as useless as it is improper to contend with God. He does his own pleasure, and deals with man as he deems best and right. The reason of his doings he does not state, nor has man any power to extort from him a statement of the causes why he afflicts us. This is still true. The reason of his doings he does not often make known to the afflicted, and it is impossible to know now the causes why he has brought on us the calamity with which we are visited. The general reasons why men are afflicted may be better known now than they were in the time of Elihu, for successive revelations have thrown much light on that subject. But when he comes and afflicts us as individuals; when he takes away a beloved child; when he cuts down the young, the vigorous, the useful, and the pious, it is often impossible to understand why he has done it.
All that we can do then is to submit to his sovereign will, and to believe that though we cannot see the reasons why he has done it, yet that does not prove that there are no reasons, or that we may never be permitted to understand them. We are required to submit to his will, not to our own reason; to acquiesce because he does it, not because we see it to be right. If we always understood the reasons why he afflicts us, our resignation would be not to the will of God, but to our own knowledge of what is right; and God, therefore, often passes before us in clouds and thick darkness to see whether we have sufficient confidence in him to believe that he does right, even when we cannot see or understand the reason of his doings. So a child reposes the highest confidence in a parent, when he believes that the parent will do right, though he cannot understand why he does it, and the parent does not choose to let him know. May not a father see reasons for what he does which a child could not understand, or which it might be proper for him to withhold from him?
