“Some Calvinist commentators point to various passages of specific events such as the selling of Joseph into slavery (Gen. 45-50), the crucifixion of Christ (Acts 2:23), and the military actions of the Assyrians (Is. 10). And they are not wrong to do so. Yet one cannot falsely generalize from these particulars and assume that God chooses to exercise His right of sovereignty in the same way for things like the moving of a finger. Perhaps He does, but perhaps He does not; perhaps He does at some times, but not at others.
“Yet to suggest such a thing hardly removes any sovereignty from God, for a simple reason that I have yet to see dealt with by a Calvinist commentator (though I may see it in the future): The decision to do nothing is itself a sovereign decision.”
