You are so careful to distinguish the covenant from the Law, but then you put "covenant" where Scripture says "Law". God does not say that He will write "the covenant" on their minds and hearts in Jeremiah 31; He says He will write "the law.
You have completely undermined your own argument.
Dino scripture does say the ten commandments are the covenant, God Himself . I did not invent this, I understand it can be a surprise, many churches never speak of this but is so important th know that the old covenant and new covenant are. it is not a vague theory, since you admitted nor reading the o.p. i will give you here the verses where GOD clearly calls the ten commandments the covenant;
Here are some the
KJV verses where
God clearly calls the Ten Commandments “the covenant.” These are direct and plain statements from Scripture.
Exodus 34:28 (KJV)
“And he was there with the LORD forty days and forty nights; he did neither eat bread, nor drink water.
And he wrote upon the tables the words of the covenant, the ten commandments.”
Deuteronomy 4:13 (KJV)
“And he declared unto you
his covenant, which he commanded you to perform,
even ten commandments; and he wrote them upon two tables of stone.”
Deuteronomy 9:9 (KJV)
“When I was gone up into the mount to receive
the tables of stone, even the tables of the covenant which the LORD made with you…”
Deuteronomy 9:11 (KJV)
“And it came to pass at the end of forty days and forty nights, that the LORD gave me the two tables of stone,
even the tables of the covenant.”
Deuteronomy 5:2 (KJV)
“The LORD our God
made a covenant with us in Horeb.”
(What follows in Deuteronomy 5 is the full listing of the Ten Commandments.)
Note the ten commandments and NOT the law of Moses was kept in the Ark of the Covenant
as for Jeremiah about the new covenant I have the following ( KJV)
The New Covenant
Jer 31:31 Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah:
Jer 31:32 Not according to the covenant that I made with their fathers in the day
that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the LORD:
Jer 31:33 But this
shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
Jer 31:34 And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more.
As for the rest of the law of Moses for gentiles the Jerusalem council was clear on this and only kept a few points of the law of Moses to protect the gentile followers from defiling themselves with sexual immorality, food sacrificed to idols ans a few more items Remember that Jesus was teaching all the commandments of the covenant, the ten commandments! Ten commandments we have to follow from the heart, most if not all denominations do teach the ten commandments today do they not?
Peace be with you.
