Something I see when I read these passages about God writing His law on Israel's hearts, is that they will all of them keep every law and statute. The Entire Law.Have you noticed that the Jeremiah prophecy speaks of "law" singular, not "laws" plural? Wouldn't the singular indicate the entire body of legislation?
Another question, what makes a "law"? Isn't a law an edict enforced by courts?
I wonder if these two questions have a bearing on your question?
I suppose Gentile believers can claim to have the "law" written on their heart if the definition of "law" is restricted to love God and love neighbor. But are they talking about the law or the fruit of the Spirit? Didn't Paul say that if we are being led by the spirit we are not under the law? Galatians 5:16-24
This is something I've been thinking about for some time now. I hear people talk about God writing His Law on gentiles hearts when they become Christians, but all I can find in the Bible is that God does this for Israel when He returns.
In the fruit of the Spirit, yes, this is fully separated from 'law', it seems to me.
These are interesting questions, what makes a Law, and is it enforced?
For 'law', I'd say this mean God's decrees, the laws and statutes of the Mosaic covenant. One might also be able to make a case for saying, "the Law and the Prophets".
Enforcement was according to the Law as well, from restitution to capital punishment, on an individual level. But there was also enforcement on a national level, that if the nation kept the law, they would receive the blessings, and if it didn't they would receive the curses.
It's interesting to me that during the millennium, it seems that Israel will receive all the blessings of their covenant.
The way I see it is that,
Isaiah 59
20 And the Redeemer shall come to Zion, and unto them that turn from transgression in Jacob, saith the Lord.
21 As for me, this is my covenant with them, saith the Lord; My spirit that is upon thee, and my words which I have put in thy mouth, shall not depart out of thy mouth, nor out of the mouth of thy seed, nor out of the mouth of thy seed's seed, saith the Lord, from henceforth and for ever.
When Jesus returns, all of Israel is reborn, and for them, this means that God not only gives them rebirth, He also writes His Law on their hearts, and they begin to perfectly keep all of the Law. And in keeping the entire Law, they receive all the blessing.
Much love!
