When Adam and Eve disobeyed God, sin came into the world. God in His mercy and grace made a way of atonement so He could forgive them and they could be reconciled. Rather than punishing Adam and Eve by death, God sacrificed an innocent animal.
The life of each creature is in its blood. So I have given you the blood of animals to pay for your sin on the altar. Blood is life. That is why blood pays for your sin.
But the blood of bulls and goats could not take away sins completely, only for a time. Only the perfect sacrifice of Yeshua could do that.
PRAY FOR ISRAEL TO ACCEPT GOD’S PROVISION OF YESHUA AS ATONEMENT FOR SIN.
