When Paul uses the word Law he means the response God requires from men, both Jew and Gentile. Those who sin without the Jewish Law will be judged without the Jewish Law, ie by the eternal, universal law.
Romans 2
12 All who
sin apart from the
law will also perish apart from the
law, and all who
sin under the
law will be judged by the
law.
IOW, law represented a result bound contract between God and Man.
After the Cross, this contract was abolished, not the law. IOW, the terms (not requirements) were null and void because the contractual obligations had been met, the result delivered.
Now, the requirements still exist (and will continue to exist as long as man exists!), but the terms have changed. The old terms were:
1. Hear the Law
2. Observe the Law
3. Realise the impossibility of meeting its requirements.
4. Realise the need for God to intervene.
5. Realise that God's solution would be the result of the promise to Abraham, analogous to Isaac, who was the result of a similar promise to Abraham:
Promise 1
The world would be blessed through Abraham's Seed
Promise 2
Abraham would have a son
Parallel for Promise 1
Israel tried to bless the world through their own seeds, resulting in the world being blessed through keeping of the Law. The result was a being put under a shackle.
Parallel for Promise 2
Abraham tried to have a son through Hagar, a slave. The result was a son born to slavery.
Bottomline, Ishmael was Abraham's effort at fulfilling Gods Promise, just as Israel's wrong observance of Torah was her effort at fulfilling Gods Promise.
How was Israel supposed to fulfill law? The way Abraham should have fulfilled God's promise, by believing it. God promised He would act, Israel should have believed. Because God did act. He sent Christ.
What became different when Christ came?
When Christ came, He made the only reparation possible, acceptable: a sinless sacrifice. Sinless because He needed to bear the sins of others. A sinful man could only bear the consequences of his own sin.
When Christ came, He gave rest, closure. The law was supposed to bring awareness of sin and dependence on God, and protection from its penalties, and closure, by giving life through union with God (there I said it). It didn't, because what could man unite with, without God sending the union partner, the destination, the Promised Land? All that Law could do was to recognise repentance, resulting in immunity, salvation, safekeeping by virtue of its pedagogic role, which was what John the Baptist taught. It could not give life, which was had by resting, abiding, in Christ.
Resting in Christ resulted in abillty to meet all the requirements of the Law.
Galatians 3
13Christ redeemed us from the curse of the Law, having become a curse for us—for it is written,
“CURSED IS EVERYONE WHO HANGS ON A TREE”—
14in order that in Christ Jesus the blessing of Abraham might come to the Gentiles, so that we would receive the promise of the Spirit through faith.
Now I can post till the cows come home, show you this motif throughout Scripture, attempt to cover different aspects of the teaching, but really, coming out with your doubts would be much easier to reach a comprehensive view... and faster.
DO post what you feel is not clear, and definitely, point out the weaknesses in the argumentation. Blessings to be had for all, me included, because we could discover fresh truths, together!
I thought law and grace actually deal with sin, and not so much against it, ie, law shows its guilt penalty, grace shows its removal thus they together produce contrition + grace (faith).
Only another view,
