The Levitical system was not designed by God to remove or forgive sins. It was preparatory for the coming of the Messiah. It was meant to show us our sinfulness, and that to be right with God, faith was necessary and a substitute sacrifice was the required payment for our sin. Jesus came as that substitute and performed the final sacrifice, the one The Law was hinting at, and as such, that old covenant is no longer necessary, and therefore it is no longer in effect. As a result, we can now draw near to God through Christ with full assurance of forgiveness!
