On this post, I will let the Bible do the talking. There are a lot of verses here. But, It's worth knowing what has been made available to us in Christ.
The other day, I was sad to realize many Christians are not living under the full redmption of Christ. Many are still believing Christ redeemed us only from ceremonial laws. That statement is a slap on Jesus' face, who spilled every drop of blood to redeemed us completly from the curse of the law. When he died, His father in heaven smiled and said, "The work of my son is perfect. His blood is fragrance to me because he fulfilled every jot of the law to forgive their sins." Yet, many of us are still saying: "Christ, when you cried 'It is finished' You didn't really finish. You only did part of the work; the ceremonial law stuff. Now, let me help you out a little bit. Let me do my best. I'll try to keep the 10 commandments and a few other things."
There is something we all need to know, when the Bible talks about the law, it's talking about the Torah. The Torah is what we know as the Pentateuch. Read the next verses and see how God compares the law given by Moses in mount Sinai---10 commandments, with slavery. And then He compares the new Covenant in Christ with freedom.
Galatians 4 21 Tell me, you who want to be under the law, are you not aware of what the law says? 22 For it is written that Abraham had two sons, one by the slave woman and the other by the free woman. 23 His son by the slave woman was born according to the flesh, but his son by the free woman was born as the result of a divine promise. 24 These things are being taken figuratively: The women represent two covenants. One covenant is from Mount Sinai and bears children who are to be slaves: This is Hagar. 25 Now Hagar stands for Mount Sinai in Arabia and corresponds to the present city of Jerusalem, because she is in slavery with her children. 26 But the Jerusalem that is above is free, and she is our mother.
What does God wants us to do with the law?... Do what Jesus couldn't accomplish?... Fulfill part of it?...
Galatians 4:30 But what does Scripture say? “Get rid of the slave woman and her son, for the slave woman’s son will never share in the inheritance with the free woman’s son.”[b] 31 Therefore, brothers and sisters, we are not children of the slave woman, but of the free woman.
The correct answer is: Get rid of it! You can't be free if you are still living under the law. The law produces slaves.
Let's take a look of another comparison between the two covenants. Notice How God says the covenant Jesus gives us, through his blood, is greater than the Torah given by Moses. Since Christ is faithful and his ministry is greater than Moses, we can rest assured that if the sins of people were covered under the old covenant, how much more our sins are errased because Jesus is faithful to forgive.
Hebrews 3 (CJB) 3 Therefore, brothers whom God has set apart, who share in the call from heaven, think carefully about Yeshua, whom we acknowledge publicly as God’s emissary and as cohen gadol. 2 He was faithful to God, who appointed him; just as “Moshe was faithful in all God’s house.”[a] 3 But Yeshua deserves more honor than Moshe, just as the builder of the house deserves more honor than the house. 4 For every house is built by someone, but the one who built everything is God. 5 Also, Moshe was faithful in all God’s house, as a servant giving witness to things God would divulge later. 6 But the Messiah, as Son, was faithful over God’s house. And we are that house of his, provided we hold firmly to the courage and confidence inspired by what we hope for.
God calls disobedient to those who do not want to depend on Christ's finished work. Instead, they want to trust on doing the works of the law. God said His people tempted Him when they saw HIM working. God was upset because His people trusted on their works more than on His work. Remeber, they were in Egypt. They worked hard all of their lives. When God brought them out, He delivered them, He fed them mana but they wanted to go back to slavery, hard work! They didn't want to receive food for free. They wanted to earn it. That is what the Bible calls sin and disobedience.
Hebrews 3:16(CJB) who were the people who, after they heard, quarreled so bitterly? All those whom Moshe brought out of Egypt. 17 And with whom was God disgusted for forty years? Those who sinned — yes, they fell dead in the Wilderness! 18 And to whom was it that he swore that they would not enter his rest? Those who were disobedient. 19 So we see that they were unable to enter because of lack of trust.
AMP Hebrews 3:19 So we see that they were not able to enter [into His rest], because of their unwillingness to adhere to and trust in and rely on God [unbelief had shut them out].
Once again, let's see the suppremacy of Christ's finished work over the law given by Moses.
AMP Hebrews 8:6 But as it now is, He [Christ] has acquired a [priestly] ministry which is as much superior and more excellent [than the old] as the covenant (the agreement) of which He is the Mediator (the Arbiter, Agent) is superior and more excellent, [because] it is enacted and rests upon more important (sublimer, higher, and nobler) promises.
The first covenant had rules men had to fulfill. It had punishment for those who didn't but it showed grace by the sacrificial system; representing Christ who would die for us. However, God found fault with the old covenant! Did He find fault because the priests were not offering sacrifices correctly? NO, He found fault because men could never do their part and God had to withdraw his favor! God didn't like disregarding His people, who were not able to obey the law given by Moses.
7 For if that first covenant had been without defect, there would have been no room for another one or an attempt to institute another one. 8 However, He finds fault with them [showing its inadequacy] when He says, Behold, the days will come, says the Lord, when I will make and ratify a new covenant or agreement with the house of Israel and with the house of Judah.
9 It will not be like the covenant that I made with their forefathers on the day when I grasped them by the hand to help and relieve them and to lead them out from the land of Egypt, for they did not abide in My agreement with them, and so I withdrew My favor and disregarded them, says the Lord.
The new law God brings speaks of faith in Christ. It's the law of faith. This means, when you sin, God will tell you, "You are righteous because you rely on what my Son has done for you." This law is not like the other law! The other law has nothing to do with faith. Galatians 3:12
Romans 3:20 Where, then, is boasting? It is excluded. Because of what law? The law that requires works? No, because of the law that requires faith.
Finally, let's take a close look to the new covenant God speaks of. Remember, it is totally different than the first one.10 For this is the covenant that I will make with the house of Israel after those days, says the Lord: I will imprint My laws upon their minds, even upon their innermost thoughts and understanding, and engrave them upon their hearts; and I will be their God, and they shall be My people. 11 And it will nevermore be necessary for each one to teach his neighbor and his fellow citizen or each one his brother, saying, Know (perceive, have knowledge of, and get acquainted by experience with) the Lord, for all will know Me, from the smallest to the greatest of them.
Look at the difference of this covenant. This is the law He writes on your heart, "Son, I don't remember your sins! Rest. You are right, judged accepted. You have been made holy, set appart by me."
12 For I will be merciful and gracious toward their sins and I will remember their deeds of unrighteousness no more.
For those who insist on living under the law, this is what God says of it. It is out of use, obsolete!
13 When God speaks of a new [covenant or agreement], He makes the first one obsolete (out of use). And what is obsolete (out of use and annulled because of age) is ripe for disappearance and to be dispensed with altogether.
