For every High Priest was chosen from among the people and appointed to represent them before God by presenting their gifts to God and offering sacrifices on their behalf.
For I have shared with you what I have received and what is of utmost importance: The Messiah died for our sins, fulfilling the prophecies of the Scriptures.
Faith moved Abel to choose a more acceptable sacrifice to offer God than his brother Cain, and God declared him righteous because of his offering of faith. By his faith, Abel still speaks instruction to us today, even though he is long dead.
This is why he had to be a man and take hold of our humanity in every way. He made us his brothers and sisters and became our merciful and faithful King-Priest before God; as the One who removed our sins to make us one with him.
Unlike the former high priests, he is not compelled to offer daily sacrifices. They had to bring a sacrifice first for their own sins, then for the sins of the people, but he finished the sacrificial system, once and for all, when he offered himself.
But since he didn’t qualify to be an earthly priest, and there are already priests who offer sacrifices prescribed by the law, he offered in heaven a perfect sacrifice.
it was an illustration that pointed to our present time of fulfillment, demonstrating that offerings and animal sacrifices had failed to perfectly cleanse the conscience of the worshiper.
