Are you an expert on Judaism? What about Yom Kippur and the day of atonement?Once again you understanding of the Messiah is your flaw in your reasoning. Christ did not come to destroy the law, he came to fulfill the law.
Christ is our sacrifice for our sins,
Do you sacrifice a perfect lamb every year?
if not Why.. if you don't according to jewish law you sins for the past and the following year are not forgiven..
