“Jesus Christ, the Incarnate Son of God, hangs upon a tree. He is murdered—murdered by His own brethren. ‘He came unto His own, and His own received Him not, but His own led Him out to death.’
He bleeds, He dies, and then is heard a cry in heaven. The astonished angels again start from their seats, and they say, ‘What is this? What is this cry that we hear?’
And the Mighty Maker answers yet again, ‘It is the cry of blood. It is the cry of the blood of My only-begotten and beloved Son!’ And God the Father, uprising from His throne, looks down from heaven and listens to the cry.
And what is the cry? It is not revenge. It is not vengeance. But the voice crieth, ‘Mercy! Mercy! Mercy!’ Did you not hear it? It said, ‘Father, forgive them, for they know not what they do.’ It said, ‘It is finished.’
Herein, the blood of Christ ‘speaketh better things than that of Abel,’ for Abel’s blood said, ‘Revenge!’ and made the sword of God start from its scabbard. But Christ’s blood cried ‘Mercy!’ and sent the sword back again and bade it sleep forever.”
