Spoiler alert!
So, it's my turn to read this week (Reformation Sunday). Mostly about the new covenant replacing the old, or as Hebrews calls it obsolete covenant. Personally, I like the first reading the best. Overall, and today.
First Reading: Jeremiah 31:31-34
Psalm: Psalm 46
Second Reading: Romans 3:19-28
Not by me-
Gospel: John 8:31-36
(Edit: The second and further edits you are about to see is me finding links for these.)
What do you think it means for the new covenant to replace the old? What does that look like in practice/application?
Starting with the relevant (to my answer) part of Jeremiah and ignoring that Jeremiah is very narrow in focus on who these contracts are with and whole lot of other stuff.
"a covenant that they broke..."
The first covenant is a broken deal. One party failed to live up to their end of the bargain, so...
Of course, this is all metaphorical because no one actually signed on to the deal except for maybe God, just like in political theory no one actual signs the contract that the "contract theorist" speak of that makes us willing to be governed.
Continuing with Hebrews 10:9
"He abolishes the first in order to establish the second"
So, the first "deal" can be nullified and voided by the party, God that didn't break the deal. But God still "wants in" so he creates a new offer. One with more favorable language. "I will be merciful toward their iniquities, and I will remember their sins no more".
Earlier in Hebrews 8:13, just after quoting (more or less) Jeremiah
"
In speaking of a new covenant, he has made the first one obsolete, and what is obsolete and growing old will soon disappear."
Of course, the big issue here is that it seems that those that were offered this new and better deal decided to try again with the old one. And those that were never part of this conversation took God up on the deal. But neither group has really allowed the old to disappear.
But the other problem is "how it works" is not really what I like. Just hashing out an answer to your question. Not sure I'd go for it either. The new covenant is just an underlying theme of those lessons.
Ultimately, it's not the old vs new covenant so much for me, but I like
I will put my law within them, and I will write it on their hearts, and I will be their God, and they shall be my people. No longer shall they teach one another or say to each other, “Know the Lord,” for they shall all know me, from the least of them to the greatest, says the Lord, for I will forgive their iniquity and remember their sin no more.
I will put my law ... on their hearts - What do we associate the heart with? When they create candy hearts do they write messages consistent with "thou shall not..." on them? Or maybe something else? (
Let's ignore that many words meaning slightly different things translate to one English word, and that the candy hearts usually drift to the wrong meaning.) So, what is written on our hearts - love. The law as it was always meant to be.
No longer shall they teach one another or say to each other, “Know the Lord,” - okay we have to work on this one.
for they shall all know me - we probably do as far as this is concerned, just long for more. Too bad about that alien kidnapping is preventing the AMA thread.
from the least of them to the greatest, - you and me fit there somewhere (ignoring that Israel part).
I will forgive their iniquity and remember their sin no more. - you know what this is missing? A requirement for me to believe anything, do anything.
What is not to like? Sign me up! Except I don't have to, because this is what a loving God would just be like. No other choice but same as it has been since day one.
This is the only God I can believe in. The only God worthy of worship and praise and thanksgiving. If there is no god at all, oh well. If God or gods exist and this is wrong, then I'm probably doomed.
