As opposed to the Old Covenant between the Jews and YHWH.
I'm aware of the new covenant - and that God promises that we will have eternal life with him - if we follow and obey. All I am saying is that God reads hearts and minds and that is how he determines whether someone will or will not be saved. Sola Gratia - salvation by the Grace of God through Faith in Christ.
If you're arguing for Sola Fidae - there are significant problems with this argument. Not the least of which is that the doctrine is ascriptural. You don't need the bible in order to be saved - one can be saved without even reading a jot.
Then why does Paul refer to the nature of the Gentiles in obedience to the Law written on their hearts as opposed to the obedience of the Jews to the Laws of Moses? One is codified, one is conscientious. God writes his laws on people's hearts prior to the new covenant. He did so at creation and it has been passed on to all of us.
That is the whole point of Romans - go back and read the book. I suppose you also reject Paul when he says that Gentiles are ingrafted branches - and that the Jews are still God's chosen people.
3) The difference between the Law of Moses being written on stone tablets, and Christ’s Law being written on the hearts of believers.
This is the crux of the issue. You don't really believe Christ when he states that 'not a stroke of the pen' has been removed from the Old Covenant. Jesus talks about how he is the fulfillment of the promises to the Jews - and that through the grace of God - salvation has been extended from the Jews to the Gentiles, as Paul speaks of later.
The days are coming,” declares the LORD,
“when I will make a new covenant
with the people of Israel
and with the people of Judah.
He specifically refers to the Jews, not the Gentiles.
You can't get there from here, jmcfast.
Says nothing there about Jesus being the mediator... all Jeremiah says is that God is going to make a New Covenant with his people Israel to replace the one that they broke.
If you're going to make the mediator argument - at least refer to Hebrews 8:6 which is the actual source, not Jeremiah which says nothing of a mediator.
Then onto Hebrews 9:11 which says this:
"But when Christ came as high priest of the good things that are now already here, he went through the greater and more perfect tabernacle that is not made with human hands, that is to say, is not a part of this creation. He did not enter by means of the blood of goats and calves; but he entered the Most Holy Place once for all "by his own blood, thus obtaining eternal redemption."
The blood of goats and bulls and the ashes of a heifer sprinkled on those who are ceremonially unclean sanctify them so that they are outwardly clean. How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God!
For this reason Christ is the mediator of a new covenant, that those who are called may receive the promised eternal inheritance—now that he has died as a ransom to set them free from the sins committed under the first covenant.
You assume far too much. It's like you're reading off a script.
Here's a clue. Drop the script. You'll be far more effective.
Now, knowing what Hebrews 9:11-15 says about the blood of Christ - let's go back to the Gospels. John 6:53-9
"Jesus said to them, “Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day. For my flesh is real food and my blood is real drink. Whoever eats my flesh and drinks my blood remains in me, and I in them. Just as the living Father sent me and I live because of the Father, so the one who feeds on me will live because of me. This is the bread that came down from heaven. Your ancestors ate manna and died, but whoever feeds on this bread will live forever.” He said this while teaching in the synagogue in Capernaum.
