Okay, When I got to the second page I found some intelligent discussion. Maybe Ill give my two cents worth. I agree with what Intrepid said but I have some to add as well.
Basically the Jews created laws out of 10 simple commandments. Basically if you follow the 1st commandment everything else falls in line.
I would say that the law was divided into Ceremonial law and moral law.
The ceremonial law was done away with, though its original purposes and its design in revealing the attributes of God to us are still valuable in our understanding of the nature of God.
As for the moral law, As we see in the Ten Commandments Jesus actually expanded them. As Intrepid pointed out Jesus said Mth 5:17 " Do not think that I came to destroy the law or the Prophets , I did not come to destroy but to FULFILL. For assuredly, I say to you till heaven and earth pass away, on jot or one tittle will by no means pass from the law till all is FULFILLED. .... For I say to you , that unless your righteousness exceeds the righteousness of the Pharisees, yo will by no means enter the kingdom of heaven.
continuing.
You have heard that it was said of old, " You shall not murder".... but I say to you that whoever is angry with his brother without a cause shall be in danger of the judgment... vs 27... You have heard that it was said to hose of old " You shall not commit adultery. But I way to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart.
Basically what I see here is that Jesus has revealed the truth of the law to mankind. The Pharisees were the "holier than thous" of that time. Proud of their "righteousness" For Jesus to say that one must surpass that level of righteousness showed how futile mans righteousness is... Is 64:6 But we are all like an unclean thing. And all our righteousness's are like filthy rags...
Jesus has revealed basically an impossible righteousness. That every thought of sin is now equal to sin. A simple look is sin. Anger or hate without cause is sin.. This is an impossible standard.
This is because Jesus fulfilled the law. Jesus became the righteousness the law required because he is the only one ever in history to be perfect and live the law perfectly and without sin.
Heb ch7 deals with Christs righteousness.
7:12 For the priesthood being changed of necessity there is also a change of the law. .... vs 16 ... who has come , not according to the law of a fleshly commandment, but according to the power of an endless life... vs 18 For on the one hand there is an annulling of the former commandment because of its weakness and unprofitableness, for the law made nothing perfect, on the other hand, there is the bringing in of a better hope, through which we draw near to God..
So the law was not profitable to perfection.. Jesus as the fulfillment of the law became that perfection on our behalf.
So basically here is how it plays out The acceptance of Christ in our lives IMPUTES HIS Righteousness into us. This is what perfects us in God's eyes. When He sees us He sees the righteous blood of His Son. We are not justified by our own work but the finished work of Christ.
Does this mean we cannot learn anything from the moral law.. Absolutely not... The Law was given to define sin. When Jesus came he clearly explained that the letter of the law barely scraped the surface of the actual righteousness required to be sinless against a Holy God. This reveals just how Holy our God is and how unrighteous we are as humans. Only through Christ can we be righteous for He was the only law keeper.
So the moral law is still important and should be followed to the best of our ability, but it will not make us righteous because our righteousness is in Christ alone, and our following of the commandments of God simply show our love for God and our desire to worship him in spirit and in truth.
I hope that sheds light on my point of view...
