How can we attribute the same work to God, to Satan, and to man?

John Calvin answers this question beautifully in The Institutes:

...Let us refer to the calamities brought upon holy Job by the Chaldeans. They having slain his shepherds, carry off his flocks. The wickedness of their deed is manifest, as is also the hand of Satan, who, as the history informs us, was the instigator of the whole. Job, however, recognises it as the work of God, saying, that what the Chaldeans had plundered, “the Lord” had “taken away.” How can we attribute the same work to God, to Satan, and to man, without either excusing Satan by the interference of God, or making God the author of the crime? This is easily done, if we look first to the end, and then to the mode of acting. The Lord designs to exercise the patience of his servant by adversity; Satan’s plan is to drive him to despair; while the Chaldeans are bent on making unlawful gain by plunder. Such diversity of purpose makes a wide distinction in the act....there is no inconsistency in attributing the same act to God, to Satan, and to man, while, from the difference in the end and mode of action, the spotless righteousness of God shines forth at the same time that the iniquity of Satan and of man is manifested in all its deformity.
