To keep this discussion in the context of the law of Moses, popular doctrine, energized by the misunderstanding that 'not being under the law anymore' means you don't have to have an obedient faith to be saved, leads people astray into a false hope that the faith in Christ that justifies (makes one righteous before God) is the faith that doesn't have to change you into a person who is now being characterized, more and more, by the new nature, but is a faith that can leave you unchanged and disobedient and it's still the faith that justifies. As I've been showing, that's not what the Bible says.
I don't agree. The doctrine of "longer being under the law" is speaking of the Law of Moses, the old covenant laws.
But that does not leave us a 'lawless' people under the new covenant which has law. Paul makes it very clear.
1Co 9:20 And unto the Jews I became as a Jew, that I might gain the Jews; to them that are under law (Law of Moses), as under law (Law of Moses),
that I might gain them that are under law (Law of Moses);
1Co 9:21 To them that are without law (Law of Moses), as without law (Law of Moses), (
being not without law to God, but under the law to Christ,) that I might gain them that are without law (Law of Moses).
Ahh....in the OP.....No the Law of YHVH is not in reality the Law of Moses, but the Law of Christ.
Paul clearly says that he was not lawless without the Law of Moses, but was under the Law of Christ (new covenant law).
It is only when we receive an incorrect teaching of 'we are not under the law' that people believe they have no law at all. They are under the Law of Christ.
Jesus gave us two that are rather like the 10 Commandments. The apostles clearly give descriptions as to how they will be carried out both the positive and the negative, just like the Law of Moses, the old covenant is laid out. The construction of the new covenant is very much the same but does not contain all the same laws.
But there is another difference that is more important to us.
The Law of Moses, being a covenant of works, says IF you do this, THEN I will do this, IF you don't, I will curse you.
But, as you pointed out so well, Abram was declared righteous before he performed any works.
We see that God made the promise to Abram before he even responded to God in faith the very first time. But if Abram hadn't gotten out of the country (the world) the promise could not have taken effect. Basically God is telling Abram to trust Him and He will bless Him.
Gen 12:1 Now the LORD had said unto Abram, Get thee out of thy country, and from thy kindred, and from thy father's house, unto a land that I will shew thee:
Gen 12:2 And I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing:
Gen 12:3 And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed.
Gen 12:4 So Abram departed, as the LORD had spoken unto him; and Lot went with him: and Abram was seventy and five years old when he departed out of Haran.
Here God says that Abram's reward is YHVH Himself.
Gen 15:1 After these things the word of the LORD came unto Abram in a vision, saying, Fear not, Abram: I am thy shield, and thy exceeding great reward.
This sounds like the new covenant to me.
