Then follows the sentence which falls into two parts--the curse of bitter, unrequited toil, and the doom of homeless wandering. The blood which has been poured out on the battlefield fertilises the soil; but Abel's blasted the earth. It was a supernatural infliction, to teach that bloodshed polluted the earth, and so to shed a nameless horror over the deed. We see an analogous feeling in the common belief that places where some foul sin has been committed are cursed. We see a weak natural correspondence in the devastating effect of war, as expressed in the old saying that no grass would grow where the hoof of the Turk's horse had stamped. The doom of wandering, which would be compulsory by reason of the earth's barrenness, is a parable. The murderer is hunted from place to place, as the Greek fable has it, by the furies, who suffer him not to rest. Conscience drives a man 'through dry places, seeking rest, and finding none.' All sin makes us homeless wanderers. There is but one home for the heart, one place of repose for a man, namely, in the heart of God, the secret place of the Most High; and he who, for his sin, durst not enter there, is driven forth into 'a salt land and not inhabited,' and has to wander wearily there. The legend of the wandering Jew, and that other of the sailor, condemned for ever to fly before the gale through stormy seas, have in them a deep truth. The earthly punishment of departing from God is that we have not where to lay our heads. Every sinner is a fugitive and a vagabond. But if we love God we are still wanderers indeed, but we are 'pilgrims and sojourners with Thee.' 9. Cain's remonstrance completes the tragic picture. 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 unrepented 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.
