There is a great mystery regarding the theme of blood sacrifice in the Bible. In Genesis, when Cain slew Abel the Bible says God heard the voice of Abel's blood crying out from the ground. This suggests that the blood has a voice. Abel is a type of Christ- the first Martyr.
What does this mean? The blood of Jesus has a voice! In fact the Bible says in Hebrews that the blood of Jesus “speaks” better things than Abel! The voice of the blood is speaking now saying you have access to the throne of grace – regardless of what you have done! NOTHING is more powerful than the blood of Jesus now speaking on your behalf and inviting you to a place above your situation.
