John Wesley on Job 11:6

Secrets - The unsearchable depths of God's wisdom in dealing with his creatures. Double - That they are far greater (the word double being used indefinitely for manifold, or plentiful) than that which is manifested. The secret wisdom of God is infinitely greater than that which is revealed to us by his word or works: the greatest part of what is known of God, is the least part of those perfections that are in him. And therefore thou dost rashly in judging so harshly of his proceedings with thee, because thou dost not comprehend the reasons of them, and in judging thyself innocent, because thou dost not see thy sins; whereas the all - knowing God sees innumerable sins in thee, for which he may utterly destroy thee.
