The New Covenant.

We first read about YHWH making a new covenant back in Jeremiah. He writes in Chapter 31, verse 31:

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.

We read the same thing in Hebrews:

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.
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:
Heb 8:11 And they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest.
Heb 8:12 For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more.
Heb 8:13 In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away.

Christians rely upon this New Covenant, but fail to read who this New Covenant is being made with. HE says " I will make with the house of Israel" HE is making HIS new covenant with those who obey HIS Commandments, and Laws.

When a person puts on Christ, and becomes a follower of the Savior, he becomes part of Israel, spiritually.

The Gentiles of old, who became part of Israel, had to conform to God's Laws. So too we, who are Gentile believers in Christ. IF we wish to partake in this New Covenant.

When we enter into the Covenant with YHWH, is goes both ways, for a covenant is a promise, from one to another. HE makes a covenant with us, to claim us as HIS bride, and as such, we take upon ourselves all of the blessings this entitles us to.
But then, we too, make a promise to HIM... that we will be obedient subjects, to HIS rules.

God's law was not the problem with the old covenant, for we read: I will put my laws into their mind, and write them in their hearts...
But what was the problem with the old covenant? What has changed from the old covenant to the old? The old was written upon stone tablets, but the new covenant is being written upon our hearts.

Obeying the LAW without the Holy Spirit is impossible. But for those who have the indwelling of the Spirit, all things are possible, and those who have the Holy Spirit love the law of YHWH.

With the Holy Spirit guiding us, and if we listen to the voice of YHWH, we will learn to avoid those things which bring temptation, and cause us to fall.

But if we do fall, not intentionally, we have the blood of Christ, our advocate, who is just, and willing to forgive.

But to sin purposely, is unforgivable, as Hebrews tells us.
Heb 6:4 For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,
Heb 6:5 And have tasted the good word of God, and the powers of the world to come,
Heb 6:6 If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.

and here

Heb 10:26 For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
Heb 10:27 But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.
Heb 10:28 He that despised Moses' law died without mercy under two or three witnesses:
Heb 10:29 Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?

Many churches today, refuse to teach this though, as it does not tickle the ear, nor will it bring in the donations they need. Instead, these wolves teach their followers that it is ok to sin, as long as you have accepted (their version) Christ into their heart. But this is an abomination and bastardization of the WORD.

Repentance is more than just saying "I'm sorry". Repentance is turning from that sin, we are told also that we must bring forth works worthy of repentance.

Act 26:20 But shewed first unto them of Damascus, and at Jerusalem, and throughout all the coasts of Judaea, and then to the Gentiles, that they should repent and turn to God, and do works meet for repentance.
