It would, no doubt, have been possible for God to remove by miracle the results of the first sin ever committed by a human being; but this would not have been much good unless He was prepared to remove the results of the second sin, and the third, and so on forever. If the miracles ceased, then sooner or later we might have reached our present lamentable situation: if they did not, then a world thus continually underpropped and corrected by Divine interference, would have been a world in which nothing important ever depended on human choice, and in which choice itself would soon cease from the certainty that one of the apparent alternatives before you would lead to no results and was therefore not really an alternative.
