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.
With how different a meaning then comes now to us this question of God's: "Where is thy brother?" Our Brother also is slain. Him Whom God sent among us to reverse the curse, to lighten the burden of this life, to be the loving member of the family on Whom each leans for help and looks to for counsel and comfort--Him Who was by His goodness to be as the dayspring from on high in our darkness, we found _too_ good for our endurance and dealt with as Cain dealt with his more righteous brother. But He Whom we slew God has raised again to give repentance and remission of sins, and assures us that His blood cleanseth from all sin. To every one therefore He repeats this question, "Where is thy brother?" He repeats it to every one who is living with a conscience stained with sin; to every one that knows remorse and walks with the hanging head of shame; to every one whose whole life is saddened by the consciousness that all is not settled between God and himself; to every one who is sinning recklessly as if Christ's blood had never been shed for sin; and to every one who, though seeking to be at peace with God, is troubled and downcast--to all God says, "Where is thy brother?" tenderly reminding us of the absolute satisfaction for sin that has been made, and of the hope towards God we have through the blood of His Son.
