The Jews were God’s people by following the works of the law. The Jews had the law of works, and in this, they were called God’s people. The works of the law, i.e. circumcision, sin offerings, and sacrifices, save no one anymore; we are saved only by faith in Jesus. The works of the law could save the Jews even if they did not have faith in God. When someone does the works of the law, it shows nothing about the condition of their heart. God nailed the written code with its regulations to the cross; we no longer have to have circumcision, or sin offerings, the observance of special days. Jesus fulfilled all the works of the law, so in faith in Jesus and His blood, that is how God saves us. To be saved, we still have to do that which is good. We still are not to do that which is evil.
