I never said it was for sinners. I said it was for God's people. American laws are for those who live in America. Icelandic laws are for those who live in Iceland. God's laws are for God's people.
This sounds nice, but I suggest it is simply not what the Bible teaches.
In the book of Leviticus, God tells the Jewish nation to not eat certain foods and He connects this instruction to a declaration that Israel has been
set apart from the
nations. A very strong indication that the Law of Moses was for one nation only.
And we need to remember who was at Mount Sinai. It was the nation of
Israel, incorporating, of course, the odd person who was not Jewish by "birth".
I have already argued in detail from Romans 3 why Paul sees the Law of Moses as being applicable to Jews only. I will know make an argument appealing to Romans 4:
Here is the relevant text from Romans 4:
Is this blessing then on (I)the circumcised, or on the uncircumcised also? For (J)we say, "(K)FAITH WAS CREDITED TO ABRAHAM AS RIGHTEOUSNESS." 10How then was it credited? While he was circumcised, or uncircumcised? Not while circumcised, but while uncircumcised; 11and he (L)received the sign of circumcision, (M)a seal of the righteousness of the faith which he had while uncircumcised, so that he might be (N)the father of (O)all who believe without being circumcised, that righteousness might be credited to them, 12and the father of circumcision to those who not only are of the circumcision, but who also follow in the steps of the faith of our father Abraham which he had while uncircumcised. 13For (P)the promise to Abraham or to his descendants (Q)that he would be heir of the world was not through the Law, but through the righteousness of faith. 14For (R)if those who are of the Law are heirs, faith is made void and the promise is nullified; 15for (S)the Law brings about wrath, but (T)where there is no law, there also is no violation. 16For this reason it is by faith, in order that it may be in accordance with (U)grace, so that the promise will be guaranteed to (V)all the descendants, not only to those who are of the Law, but also to (W)those who are of the faith of Abraham, who is (X)the father of us all, 17(as it is written, "(Y)A FATHER OF MANY NATIONS HAVE I MADE YOU") in the presence of Him whom he believed, even God, (Z)who gives life to the dead and (AA)calls into being (AB)that which does not exist.
What is Paul's basic argument here? That the true family of God includes both Jews and Gentiles. Paul starts out by stressing that the promised blessing to Abraham's descendents was given
before Abraham was marked out by circumcision as father of the
nation of Israel. This is absolutely vital to Paul's argument - he wants to make a case that, despite what some Jews may think, the "real" family of Abraham, at least in the sense that is relevant to those who are justified by faith, includes both Jew and Gentile. And this same idea is repeated over and over and over in this text - Abraham's "true" descendents include
both Jew
and Gentile. Fine.
Now for the relevant point. It is clear beyond dispute (although I suspect you will dispute this anyway) from verse 16 that Pauls sees
Jews as those who are "of the Law". If he believed that Gentiles were "of the Law" as well, his argument would not make any sense at all.
If you are right - if the Law of Moses is for both Jew and Gentile - look at what you have Paul saying in verse 16:
all the descendants, not only to those who are of the Law (that is all believers, Jew or Gentile), but also to those who are of the faith of Abraham
So, please tell us, exactly who are these "of the faith of Abraham"? On your take that the Law of Moses applies to Gentile believers as well as to Jewish ones, there is no believer who is
not "of the law". So who is Paul talking about when he clearly marks out a
different group as being those "of the faith of Abraham"?
I politely suggest that
this is the proper interpretation:
all the descendants, not only to those who are of the Law (that is, Jewish believer), but also to those who are of the faith of Abraham (that is, Gentile believers who, while not "ethnic" children like Jews, do indeed share Abraham's faith).
