(Hebrews 8:6-7) points out that the system of animal sacrifice was incomplete
as it required repeated sacrifices. Animal sacrifices were commanded by God
so that the individual could experience forgiveness of sin. The animal served as
a substitute—that is, the animal died in place of the sinner, but only temporarily
which is why the sacrifices needed to be offered over and over. Animal sacrifices
have stopped with Jesus Christ. Jesus Christ was the ultimate sacrificial substitute
once for all time (Hebrews 7:27) and is now the only mediator between God and humanity.
