Are you saying that any of the NT writings are not the God-breathed word of God?
Okay, let's examine the terms of this covenant to see what it says.
Please give the terms of this covenant.
What are the terms of the New Covenant?
Heb 8:8 For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make
a new covenant with the house of Israel and with the house of Judah:
OK, we are talking about the New Covenant here...
Heb 8:9 Not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they continued not in my covenant, and I regarded them not, saith the Lord.
Why did He need to make a New Covenant? Were the terms and conditions of the Old Covenant wrong. Did God make a mistake? Did He foul up the Old Covenant? Was there something inherently wrong with the Covenant itself?
Heb 8:8
For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah:
Heb 8:9 Not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt;
because they continued not in my covenant, and I regarded them not, saith the Lord.
The problem was not the Covenant nor was it the terms and conditions of it, the problem was with the people...
Heb 3:10 Wherefore I was grieved with that generation, and said,
They do alway err in their heart; and they have not known my ways.
So, to rectify this situation, what is God doing?
Heb 8:10 For this is the covenant that I will make with the house of Israel after those days, saith the Lord;
I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:
Now what Laws? Same Laws or different Laws? The scripture nowhere says there is anything wrong with God's Law, it says there is something wrong with us. Paul explains that...
Rom 7:12 Wherefore the law is holy, and the commandment holy, and just, and good.
Rom 7:14 For we know that the law is spiritual: but I am carnal, sold under sin.
To quote Pogo (I am telling my age here)...
"We have met the enemy... and he is us"
So what does God do? Throw out a Law that is spiritual, that is holy and just and good? Or does He change us so that we may live by His Law?
Eze 36:24 For I will take you from among the heathen, and gather you out of all countries, and will bring you into your own land.
Eze 36:25 Then will I sprinkle clean water upon you, and ye shall be clean: from all your filthiness, and from all your idols, will I cleanse you.
Eze 36:26 A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh.
Eze 36:27 And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.
Heb 10:12 But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God;
Heb 10:13 From henceforth expecting till his enemies be made his footstool.
Heb 10:14 For by one offering he hath perfected for ever them that are sanctified.
Heb 10:15 Whereof the Holy Ghost also is a witness to us: for after that he had said before,
Heb 10:16 This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them;
Heb 10:17 And their sins and iniquities will I remember no more.
Heb 10:18 Now where remission of these is, there is no more offering for sin.
Heb 10:19 Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus,
Heb 10:20 By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh;
Heb 10:21 And having an high priest over the house of God;
Notice what happens? The Law is not thrown out, but rather we are given a heart to obey and God forgives our sins and iniquities by the remission of sin through the Sacrifice of Christ.
