The law to which Adam is to be obedient is in the simplest form. There is restriction. Thou shalt not' is the first form of law, and it is a form congruous with the undeveloped, though as yet innocent, nature ascribed to him. The conception of duty is present, though in a very rudimentary shape. An innocent being may be aware of limitations, though as yet not knowing good and evil.' With deep truth the story represents the first suggestion of disobedience as presented from without. No doubt, it might have by degrees arisen from within, but the thought that it was imported from another sphere of being suggests that it is alien to true manhood, and that, if brought in from without, it may be cast out again. And the temptation had a personal source. There are beings who desire to draw men away from God. The serpent, by its poison and its loathly form, is the natural symbol of such an enemy of man. The insinuating slyness of the suggestions of evil is like the sinuous gliding of the snake, and truly represents the process by which temptation found its way into the hearts of the first pair, and of all their descendants. For it begins with casting a doubt on the reality of the prohibition. Hath God said?' is the first parallel! opened by the besieger. The fascinations of the forbidden fruit are not dangled at first before Eve, but an apparently innocent doubt is filtered into her ear. And is not that the way in which we are still snared? The reality of moral distinctions, the essential wrongness of the sin, is obscured by a mist of sophistication. There is no harm in it' steals into some young man's or woman's mind about things that were forbidden at home, and they are half conquered before they know that they have been attacked. Then comes the next besieger's trench, much nearer the wall--namely, denial of the fatal consequences of the sin: Ye shall not surely die,' and a base hint that the prohibition was meant, not as a parapet to keep from falling headlong into the abyss, but as a barrier to keep from rising to a great good; for God doth know, that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods.' These are still the two lies which wile us to sin: It will do you no harm,' and' You are cheating yourselves out of good by not doing it.'
