And while it is not ours to explain how God in His secret counsel rules and overrules the sinful acts of men, it is ours to know that whatever God does He never deviates from His own perfect justice. In all the manifestations of His character He shows Himself pre-eminently the Holy One. These deep workings of God are mysteries which are to be adored, but not to be inquired into; and were it not for the fact that some persons persist in declaring that the doctrine of Predestination makes God the author of sin, we could let the matter rest here.
A partial explanation of sin is found in the fact that while man is constantly commanded in Scripture not to commit it, he is, nevertheless, permitted to commit it if he chooses to do so. No compulsion is laid on the person; he is simply left to the free exercise of his own nature, and he alone is responsible. This, however, is never a bare permission, for with full knowledge of the nature of the person and of his tendency to sin, God allows him or allows him to be in a certain environment, knowing perfectly well that the particular sin will be committed. But while God permits sin, His connection with it is purely negative and it is the abominable thing which he hates with perfect hatred. The motive which God has in permitting it and the motive which man has in committing it are radically different. Many persons are deceived in these matters because they fail to consider that God wills righteously those things which men do wickedly. Furthermore, every person's conscience after he has committed a sin tells him that he alone is responsible and that he need not have committed it if he had not voluntarily chosen to do so.
The Reformers recognized the fact that sin, both in its entrance into the world and in all its subsequent appearances, was involved in the divine plan; that the explanation of its existence, so far as any explanation could be given, was to be found in the fact that sin was completely under the control of God; and that it would be overruled for a higher manifestation of His glory. We may rest assured that God would never have permitted sin to have entered at all unless, through His secret and overruling providence, He was able to exert a directing influence on the minds of wicked men so that good is made to result from their intended evil. He works not only all the good and holy affections which are found in the hearts of His people, but He also perfectly controls all the depraved and impious affections of the wicked, and turns them as He pleases, so that they have a desire to accomplish that which He has planned to accomplish by their means. The wicked so often glory in themselves at some accomplishment of their purposes; but as Calvin says, "the event at length proves that they were only fulfilling all the while that which had been ordained of God, and that too, against their own will, while they knew nothing of it." But while God does overrule the depraved affections of men for the accomplishment of His own purposes, He nevertheless punishes them for their sin and makes them to stand condemned in their own consciences.
