I see you miss the distinction and therefore the importance of Jesus. Keeping the Law IS about perfection. Otherwise what do you do to Gods Law?? You bring it down to something that we can persevere in? A pseudo righteousness? And what have you done to the cross of Christ by saying it is not a matter of perfection but of perseverence? If we all just persevere did we need the Lord Jesus to die upon the cross? We most assurredly do need Jesus if it is about perfection. Because without Jesus we can do nothing. Don't you see the danger in leading people back to the Law?? Don't you know about yokes and burdens??

Modern people make the mistake of thinking that the opposite of Law is grace. This could not be FARTHER from the truth! The opposite of Law is lawlessness. Even though Israel had been given the Law, God continually acted toward them in a gracious manner. Gods' very choice of Israel as the recipient of the Law and the covenants was entirely gracious. Jesus is necessary mainly because Gentiles were without God, having no covenant and no relationship with Him. Through Jesus' life and death the grace of God was extended to the Gentiles. As Paul says, at the end of time Jesus will be judge of both Jew and Gentile. As Matthew records from the lips of Jesus, the basis of his judgment is righteousness (sheep and goats). As Paul again says in Romans- no one is righteous without grace from God, and that grace is through faithfulness.
Jesus, Peter, Paul, James, and many more observed Torah, but of course they were Jews- why wouldn't they keep Torah!?
