We see in it despair without penitence. He has no word of confession. If he had accepted his chastisement, and learned by it his sin, all the bitterness would have passed away. But he only writhes in agony, and adds, to the sentence pronounced, terrors of his own devising. God had not forbidden him to come into His presence. But he feels that he dare not venture thither. And he was right; for, whether we suppose that some sensible manifestation of the divine presence is meant by Thy face' or no, a man who had un-repented sin on his conscience, and murmurings in his heart, could not hold intercourse with God; nor would he wish to do so. Thus we learn again the lesson that sin separates from our Father, and that chastisements, not accepted as signs of His love, build up a black wall between God and us.
Nor had Cain been told that his life was in danger. But his conscience made a coward of him, as of us all, and told him what he deserved. There were, no doubt, many other children of Adam, who would be ready to avenge Abel's death. The wild justice of revenge is deep in the heart of men; and the natural impulse would be to hunt down the murderer like a wolf. It is a dreadful picture of the defiant and despairing sinner, tortured by well-founded fears, shut out from the presence of God, but not able to shut out thoughts of Him, and seeing an avenger in every man.
We need not ask how God set a mark on Cain. Enough that His doing so was a merciful alleviation of his lot, and teaches us how God's long-suffering spares life, and tempers judgment, that there may still be space for repentance. If even Cain has gracious protection and mercy blended with his chastisement, who can be beyond the pale of God's compassion, and with whom will not His loving providence and patient pity labor? No man is so scorched by the fire of retribution, but many a dewy drop from God's tenderness falls on him. No doubt, the story of the preservation of Cain was meant to restrain the blood-feuds so common and ruinous in early times; and we need the lesson yet, to keep us from vengeance under the mask of justice. But the deepest lesson and truest pathos of it lies in the picture of the watchful kindness of God lingering round the wretched man, like gracious sunshine playing on some scarred and black rock, to win him back by goodness to penitence, and through penitence to peace.
