The new covenant was actually God’s original plan. What we call the “old covenant” was actually man’s idea thinking he could save himself by his own strength and effort. It was not a faith response. (See Heb. 4:2) Man’s effort failed, so in what we call the New Testament God re-introduces His original plan from the Old Testament, and says “Are you ready to give up trying to do it on your own? and let me write my law on your heart Myself?
The fault of the people was in trying to keep the law in their own power. God made a covenant with the people, and instead of them asking for God’s help they confidently replied,
“We will do everything the Lord has commanded.” Exodus 19:8
God knew this was never going to work from the get-go. He knew they could not keep His Law in their own power. This is why God says in the Old Testament book of Jeremiah 31:33,
“But this is the new covenant I will make with the people of Israel on that day,” says the Lord. “I will put my instructions deep within them, and I will write them on their hearts. I will be their God, and they will be my people.
The old covenant was not called old because it was the first covenant. It was called old because it was a useless covenant that God never asked them to make.
He never asked us to keep the commandments on our own. This is what Paul is talking about in Hebrews 8:6 when He says the new covenant is, “based on better promises.”
In the “old” covenant the people in Exodus 19:8 were the ones making promises God never asked them to make. The new covenant is based on better promises because they are God’s promises!
And because of his glory and excellence, he has given us great and precious promises. These are the promises that enable us to share his divine nature and escape the world’s corruption caused by human desires. 2 Peter 1:4
The law was never the problem. The problem was the people and their worthless promises. We find the new and better covenant based on better promises in Jeremiah 31:33 when God is promising to write and establish the perfect law in the hearts of men, not by their own power and promises, but by His power and promises. (That's the "new" or "better" of it)
Heb 8:13
13 In that He says, "A new [covenant]," He has made the first obsolete. Now what is becoming obsolete and growing old is ready to vanish away.
This verse in context is referring to the sacraficial system which included "duties" of the high priests. You inserted (covenant).
Jesus is our high priest and the sacrificial system became obsolete and vanished away. Not God's eternal law.
Matthew 5
17 “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. 18 For truly I tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished.
I said
CHRIST CHANGED THE LAW-HE FULFILLED IT THEN HE CHANGED IT
Heb 7:12-16
12 For the priesthood being changed, of necessity there is also a change of the law.
13 For He of whom these things are spoken belongs to another tribe, from which no man has officiated at the altar.
14 For it is evident that our Lord arose from Judah, of which tribe Moses spoke nothing concerning priesthood.
15 And it is yet far more evident if, in the likeness of Melchizedek, there arises another priest
16 who has come, not according to the law of a fleshly commandment, but according to the power of an endless life.
Heb 7:18-19
18 For on the one hand there is an annulling of the former commandment because of its weakness and unprofitableness,
19 for the law made nothing perfect; on the other hand, there is the bringing in of a better hope, through which we draw near to God.
Heb 7:22
22 by so much more Jesus has become a surety of a better covenant.
Heb 7:28
28 For the law appoints as high priests men who have weakness, but the word of the oath, which came after the law, appoints the Son who has been perfected forever.
Heb 7:12
12 For the priesthood being changed, of necessity there is also a change of the law.
Heb 8:7
7 For if that first covenant had been faultless, then no place would have been sought for a second.
Jude 1:24-25
24 Now to Him who is able to keep you from stumbling, and to present you faultless before the presence of His glory with exceeding joy,
25 To God our Savior, who alone is wise, be glory and majesty, dominion and power, both now and forever. Amen.
Gal 5:1-5
1 Stand fast therefore in the liberty by which Christ has made us free, and do not be entangled again with a yoke of bondage.
2 Indeed I, Paul, say to you that if you become circumcised, Christ will profit you nothing.
3 And I testify again to every man who becomes circumcised that he is a debtor to keep the whole law.
4 You have become estranged from Christ, you who attempt to be justified by law; you have fallen from grace.
5 For we through the Spirit eagerly wait for the hope of righteousness by faith.
James 2:10
10 For whoever shall keep the whole law, and yet stumble in one point, he is guilty of all.
James 2:12-13
12 So speak and so do as those who will be judged by the law of liberty.
13 For judgment is without mercy to the one who has shown no mercy. Mercy triumphs over judgment.
Matt 6:14-15
14 "For if you forgive men their trespasses, your heavenly Father will also forgive you.
15 "But if you do not forgive men their trespasses, neither will your Father forgive your trespasses.
Gal 6:2-5
2 Bear one another's burdens, and so fulfill the law of Christ.
3 For if anyone thinks himself to be something, when he is nothing, he deceives himself.
4 But let each one examine his own work, and then he will have rejoicing in himself alone, and not in another.
5 For each one shall bear his own load.
Rom 2:12
12 For as many as have sinned without law will also perish without law, and as many as have sinned in the law will be judged by the law
Gal 6:2
2 Bear one another's burdens, and so fulfill the law of Christ.

XXX Christ didnt do away with the idea of law. He just came to deliver us from the old testament law of sin and death. And He done it with the new testament law of Christ. One cant keep them both. One cant get an eye for an eye and turn the other cheek both at the same time. Jesus fulfilled the old testament law, then He changed the law.
Matt 5:17-18
17 "Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill.
18 "For assuredly, I say to you, till heaven and earth pass away, one jot or one tittle will by no means pass from the law till all is fulfilled.

23 "Woe to you, scribes and Pharisees, hypocrites! For you pay tithe of mint and anise and cummin, and have neglected the weightier matters of the law: justice and mercy and faith. These you ought to have done, without leaving the others undone.

Luke 10:26-28
26 He said to him, "What is written in the law? What is your reading of it?"
27 So he answered and said," 'You shall love the Lord your God with all your heart, with all your soul, with all your strength, and with all your mind,' and 'your neighbor as yourself.'"
28 And He said to him, "You have answered rightly; do this and you will live."

Luke 16:16-17
16 "The law and the prophets were until John. Since that time the kingdom of God has been preached, and everyone is pressing into it.

21 "but they have been informed about you that you teach all the Jews who are among the Gentiles to forsake Moses, saying that they ought not to circumcise their children nor to walk according to the customs.
