By [having] faith, Abel offered to God a better sacrifice than Cain did. [And] because of his faith he was commended by God for being righteous, when God expressed approval of his offerings. By means of his faith, Abel still speaks [to us], even though he is dead.

and to Jesus, the Mediator of a New Agreement [between God and mankind], and to the sprinkled blood [of Jesus], which says better things [to us] than [the blood of] Abel did. [Note: The contrast seems to be that "Abel's blood called for vengeance and death (See Gen. 4:10) whereas the blood of Christ provides mercy and life"].
