The old system in the law of Moses was only a shadow of the things to come, not the reality of the good things Christ has done for us. The sacrifices under the old system were repeated again and again, year after year, but they were never able to provide perfect cleansing for those who came to worship.
Christ said, "You did not want animal sacrifices or grain offerings or animals burned on the altar or other offerings for sin, nor were you pleased with them" (though they are required by the law of Moses).
