Romans 7:4

Therefore, my fellow believers, you too died to the Law through the (crucified) body of Christ, so that you may belong to another, to Him who was raised from the dead, in order that we may bear fruit for God.  

Jesus came to set us free from the law.  That is why Jesus died for our sins once and for all and sent the Holy Spirit.  The Holy Spirit is our helper and guide, keeping us away from evil.  To remain righteous under the law was difficult without help which is why sacrifices had to be offered.  Praise the Lord. Jesus redeems us on the cross.
