Anyway this lower law continued with Israel who kept their records and histroy of their people. And we saw Israel when they were obedient be very strong and successful, and then becoming wicked and being carried away captive. The Messiah came down through the line of Judah, who was the law given. So because of his lineage, Christ rightfully was a law giver. Since The old law of Moses which was only to be a prepartory law. This lower law which Paul continually in his letters teaches that if one accepts the restored gosple that Christ brought, then those who are bound by tradition by the lower laws are as filthy rags compared with the higher laws Christ brought. The lower laws could never bring us to perfection. They were obeyed by tradition and had little to do with faith. Christ brought the laws which we have to live by faith. Example, the old law states thou shalt not commit adultery. If one disobeyed this law, and they were caught, were stoned to death. Where as Christ taught that if one commits adultery in their heart has already commited the sin. And being stoned to death is not an automatic punishment, as when Christ showed the woman who was taken in adultery.
At the time of Christ, even the lower laws Jews were following was in apostacy. So Christ came to fulfill the law, and bring it back to what on the earth during different times of biblical history.
