If, therefore, you continue at war with God it is not because you must not do otherwise: if you go forward to any new thought, plan, or action unpardoned; if acceptance of God's forgiveness and entrance into a state of reconciliation with Him be not your first action, then you must thrust aside His counsel, backed though it is with every utterance of your own reason. Some of us may be this day or this week in as critical a position as Cain, having as truly as he the making or marring of our future in our hands, seeing clearly the right course, and all that is good, humble, penitent and wise in us urging us to follow that course, but our pride and self-will holding us back. How often do men thus barter a future of blessing for some mean gratification of temper or lust or pride; how often by a reckless, almost listless and indifferent continuance in sin do they let themselves be carried on to a future as woful as Cain's; how often when God expostulates with them do they make no answer and take no action, as if there were nothing to be gained by listening to God--as if it were a matter of no importance what future I go to--as if in the whole eternity that lies in reserve there were nothing worth making a choice about--nothing about which it is worth my while to rouse the whole energy of which I am capable, and to make, by God's grace, the determination which shall alter my whole future--to choose for myself and assert myself.
(3) The writer to the Hebrews makes a very striking use of this event. He borrows from it language in which to magnify the efficacy of Christ's sacrifice, and affirms that the blood of Christ speaketh better things, or, as it must rather be rendered, crieth louder than the blood of Abel. Abel's blood, we see, cried for vengeance, for evil things for Cain, called God to make inquisition for blood, and so pled as to secure the banishment of the murderer. The Arabs have a belief that over the grave of a murdered man his spirit hovers in the form of a bird that cries "Give me drink, give me drink," and only ceases when the blood of the murderer is shed. Cain's conscience told him the same thing; there was no criminal law threatening death to the murderer, but he felt that men would kill him if they could. He heard the blood of Abel crying from the earth. The blood of Christ also cries to God, but cries not for vengeance but for pardon. And as surely as the one cry was heard and answered in very substantial results; so surely does the other cry call down from heaven its proper and beneficent effects. It is as if the earth would not receive and cover the blood of Christ, but ever exposes it before God and cries to Him to be faithful and just to forgive us our sins. This blood cries louder than the other. If God could not overlook the blood of one of His servants, but adjudged to it its proper consequences, neither is it possible that He should overlook the blood of His Son and not give to it its proper result.
If then you feel in your conscience that you are as guilty as Cain, and if sins clamour around you which are as dangerous as his, and which cry out for judgment upon you, accept the assurance that the blood of Christ has a yet louder cry for mercy. If you had been Abel's murderer, would you have been justly afraid of God's anger? Be as sure of God's mercy now. If you had stood over his lifeless body and seen the earth refusing to cover his blood, if you felt the stain of it crimson on your conscience and if by night you started from your sleep striving vainly to wash it from your hands, if by every token you felt yourself exposed to a just punishment, your fear would be just and reasonable were nothing else revealed to you. But there is another blood equally indelible, equally clamorous. In it you have in reality what is elsewhere pretended in fable, that the blood of the murdered man will not wash out, but through every cleansing oozes up again a dark stain on the oaken floor. This blood can really not be washed out, it cannot be covered up and hid from God's eye, its voice cannot be stifled, and its cry is all for mercy.
