Whose blood speaks to your heart?
And he said, What hast thou done? the voice of thy brother’s blood crieth unto me from the ground. (Genesis 4:10 KJV)
God confronted Cain about his sin. Not because God did not know what Cain had done, but rather because God knew Cain killed his brother and the blood of his brother Abel was crying out from the ground bringing conviction to Cain because of his horrible sin. God desired to hear Cain confess his sin, but Cain chose to face God in indignation and disrespect, rather than acknowledge his own personal sin. Cain lashed out at God with a question about his brother rather than reaching out in fellowship to God in a personal response regarding his own sin.
Jesus Christ shed His precious blood in physical death. Jesus was killed in the flesh by the Roman soldiers who were responsible for carrying out the act of murder, however, both you and I and all mankind must take personal responsibility or blame for our part in the cruel death Jesus faced upon the cross. It was our own personal sin; past, present, and future that moved God, through love, to offer His only Son Jesus Christ’s shed blood upon the cross for payment or satisfaction of the entire debt of sin. Our sin placed Jesus Christ upon the cross.
Jesus Christ’s blood did not call out to mankind from the ground. Jesus Christ’s blood rings out offering new spiritual life from the cross of Calvary.
Cain’s blood called out from the ground about death.
