Now we know that the author of Deuteronomy had two at least of the ancient historical narratives before him which are combined in Exod. iv.-xi., and he takes up their thinking. Expressed in modern language, the thought is this. When men are found following their own will in defiance of all law and all the restraints of righteousness, that is manifestly not the first stage in their moral declension. This obstinacy in evil is the result and the wages of former evil deeds, beginning perhaps only with careless laxity, but gathering strength and virulence with every wilful sin. Until near the end of a completed growth in wickedness no man deliberately says, "Evil, be thou my good." Nevertheless each act of sin involves a step towards that, and the sinner in this manner hardens himself against all warning. Like the sins which work this obduracy, this hardening is the sinner's own act. The ruin which falls upon his moral nature is his own work. That is the inexorable result of the moral order of the universe, and from it no exception is possible. But if so, God too has been active in all such catastrophes. He has so framed and ordered the world that indulgence in evil must harden in evil. This it was which the Israelite religious mind saw and dwelt upon, as well as upon man's share in the dread process of moral decay. We also do well to take heed to this aspect of the truth. When we do, we have solved the Scriptural difficulty regarding the Divine hardening of man's heart. It is simply the ancient formula for what every mind that is ethically trained recognises in the world to-day. Those who recognise themselves as children of God, and acknowledge the obligations of His law, are dealt with in the way of discipline with infinite love and patience. Those who definitely set themselves against the moral order of the world which God has established are broken in pieces and destroyed. Between these two classes there are the morally undetermined, who ultimately turn either to the right hand or to the left. The process by which these pass on to be numbered among the rebellious is pictured in Scripture with extraordinary moral insight. The only difference from a present-day description of it is, that here God is kept constantly present to the mind as the chief factor in the development of the soul. To-day, even those who believe in God are apt to forget Him in tracing His laws of action. But that is an error of the first magnitude. It darkens the hope of man; for without a sure promise of Divine help there is no certainty of moral victory either for the race or the individual. It narrows our view of the awful sweep of sin; for unless we see that sin affects even the Ruler of the universe, and defies His unchanging law, its results are limited to the evil that we do our fellow-men, which, as we see it, is of little importance. Further, it degrades moral law to a mere arbitrary dictum of power, or to an opinion founded upon man's purblind experience.
