That's good Neuropteron. I notice that Hebrews 9:15 does not actually use the term replace just the term 'New' so I'd have to think more about that.
At any rate I need to take time to examine the book pearl was quoting from which took me by surprise. It covers this subject among others and uses unusual turns of phrase, probably translated from another language. Its going to take a lot of effort for me. I need to go through that.
I follow what you're saying, but this passage begins with the phrase "You Israelites who live in the land..." They are exiled from the land, and then once again after 70 years some are returned to rebuild the temple and start serving again.
[Deu 30:3-4 NIV] 3 then the LORD your God will restore your fortunes and have compassion on you and gather you again from all the nations where he scattered you. 4 Even if you have been banished to the most distant land under the heavens, from there the LORD your God will gather you and bring you back.
I think the above illustrates the problem with saying that law has been abolished. It might be temporarily suspended.
[Deu 31:29 NIV] 29 For I know that after my death you are sure to become utterly corrupt and to turn from the way I have commanded you. In days to come, disaster will fall on you because you will do evil in the sight of the LORD and arouse his anger by what your hands have made."
And then one or two generations later they would return. To this day there are still Jews, one of the oldest surviving groups from that time thousands of years ago. If the law ends then they have been keeping it for a long time for something that has ended.
Children are not held responsible for what parents do. One generation may be the one that brings trouble, and another may be that which returns to doing the law. Maybe it sounds to you terrible and like they were murderous, but if so it was one generation.
God requires things done his way, but we often cannot meet the challenge. God is not like humans. We tend to have a 'Last straw' whereas God would have us forgive endlessly.
The difference according to Deuteronomy is that this covenant with the Jews is promised to be renewed with succeeding generations even if current ones break it. This is why I think that a renewed and expanded covenant is more in keeping with the scene than an abolished and replaced one.
That being said, I have to say I'm still learning; so I'm not saying that I'm someone to follow on this. I do not think that the law (of Moses) can be abolished. It is like a monument. I think that the law for the gentiles can and can be replaced with spiritual living.
