Now your starting to post like me handy...
Hard isn't it? When one thing is tied to another, and then yet another...its hard to pick a place to leave off.
I think you would be correct in your statement to say that both grace and law have changed. Because I personally cannot see how one would change without the other changing also.
But I find something interesting in your post. Notice what you said about the difference in the Spirit being on "one" person verses like it is now where He is in all who believe. Then look at the correlation of the law. It was given to "one" people, and even deeper than that, only "one" person fulfilled it to the degree it was established. But now consider what the "new" covenant declares. We "all" have the law on our hearts, and we all have the Spirit.
I think we need to discern what "law" we are speaking of when we declare the law has changed. Because even though grace has changed, it has only changed one form, and that is how it is applied. So the necessity that the two are linked together would dictate that the law has changed in the same fashion. And does this line up with the context of the Bible as a whole? I think so.
I think what we see is that from the beginning onward we see the "plan" of God unfolding, or unrolling like a scroll. Each turn of the handle reveals something more. So it could look like a change, but in the essence it is not a change but a deeper understanding of the meaning.
I think just like the law has been lumped together in one "thing" and not rightfully given the separation it requires between the ordinances of Moses and the testimony of God; so too grace has been lumped together with outward manifestation of it, the presence of God and the work He does in our life. Think that over for a moment.
There was the "Law" of God. It contained within it all the rules, regulations, ordinances, testimonies; precepts. There was the outward
doing and the inward
obeying that was present. It was, at that time, a "outward to inward" direction. This fulfilled a purpose by determining that all mankind was unable to "do this".
Then there was the "Grace" of God. It was an
spiritual manifestation of God's
presence. A spiritual presence of God. At that time, it was present for those who came to the conclusion that they could not "save" themselves from the flesh side. It was seen in the promise of a Messiah.
Now go forward in the 'plan'. Christ came in the flesh. What happened to the "law"? It was stripped from the flesh. What happened to "grace"? It inhabited the flesh. But wait, the law was stripped from the flesh, the "fleshly" power to do it, and then placed into the heart.
So that would dictate that grace also underwent a transformation? Well yes, it took on a 'visual'(physical) appearance. Christ was full of truth and grace. So now, from a 'fleshly' perspective, grace is in full view, whereas before it was just spiritually discerned. That is why most people view it as they do
today, why it is held in such high regard. In fact, if you contemplate it, people nowadays hold grace up just like the pharisees held the law up in their time. And the opposite is true, just like most shun the truth of the testimony of God now, they shunned the truth of grace back then. Its all on how its viewed; fleshly or spiritually.
But wait, does that mean that it has no spiritual significance now? Absolutely not! It does, and we see it when the now
spiritually predominant 'law' written on our hearts is "broken". Grace flows out of a manifested form to the Spiritual form. But think on that for a moment. If grace is still the same grace, just different forms...then the law is still the law, just in different forms.
The law now, written on our hearts, is spiritual in nature. But, just like grace is seen when the spiritual side starts to "slide"(sin), the law is seen when the fleshly side starts to "slide"(sin).
See there is a direct relationship between them. But we think of them being "opposed" to each other because in all reality they are on "opposite" sides. Its like having a card that is red on one side and white on the other. When you "flip" it, the colors remain, but they are viewed from a different angle. But if you just told a person
"hey I have a card that has red and white on it" they might not understand the relationship of the colors to the card. It would only be by the process of going from one side to the other that they would understand what you meant.
And what did they look forward too back in the OT? What was the first thing Jesus did when He 'finished' the work and died?
He went and showed them the other side of the card.
Make sense? Grace is still the same grace just in different form,
but not function. The law is still the law just in different form,
but not function.
The "baby"? I think its the Testimony of the Living God. The declaration of who He is. Throw the law out and you can easily throw His testimony out. Throw grace out and you can easily throw His testimony out. You quote one passage, but we also have other passages that state the same.
Ecc 12:13 The end of the matter; all has been heard. Fear God and keep his commandments, for this is the whole duty of man.
So which one is right?
Both of course! It just depends on which side of the card your looking at...
