The Bible tells us we have come to this blood of sprinkling.

You have come to...Jesus, the Mediator of a new covenant, and to the sprinkled blood which speaks (of mercy), a better and nobler and more gracious message than the blood of Abel (which cried out for vengeance).

Hebrews 12:24 - Amplified.

We have a remarkable declaration in this scripture - the declaration that the sprinkled blood of Jesus speaks of mercy. It is a noble and gracious message His blood speaks because it speaks of covenant mercy. It speaks of the mercy that we find in our New Covenant relationship with God, the Father.

In contrast, the blood of Abel spoke for vengeance. In Genesis we read that God confronted the murderer Cain with these words,

What have you done? The voice of your brother's blood cries out to Me from the ground.

Genesis 4:10 - NKJV.

These words from God tell us of a specific cry to Him from a specific blood on a specific place. These words in Genesis introduce us to the principle the writer of Hebrews reveals to us.

Abel's blood spoke for vengeance and now the sprinkled blood of Jesus speaks for mercy - covenant mercy. Jesus' blood has no need to speak from the ground as Abel's did, instead it speaks from every place He sprinkled it when He ratified the New Covenant! (See Hebrews 9:19-24.)
