Galatians 6:2 NIV Carry each other’s burdens, and in this way you will fulfill the law of Christ.
There is much debate among Christians about our requirements for obeying the Law as presented in the Old Testament. The Law they are talking about is really all of the rules and regulations that God gave Moses (including the Ten Commandments) during the wilderness wanderings of the Israelites.
The key to understanding the relationship betweening the Christian and the Law is knowing that the Old Testament law was given to the nation of Israel, not to Christians. Some of the laws were to reveal to the Israelites how to obey and please God (the Ten Commandments Exodus 20:1-17,). Some of the laws were to show the Israelites how to worship God and atone for sin (the sacrificial system Numbers 15). Some of the laws were intended to make the Israelites distinct from other nations (the food and clothing rules Leviticus 11, 13, 19, ). The Old Testament law is not binding on Christians today. When Jesus died on the cross, He put an end to the Old Testament law.
Romans 10:4 NIV Christ is the culmination of the law so that there may be righteousness for everyone who believes.
Galatians 3:23-25 NIV Before the coming of this faith, we were held in custody under the law, locked up until the faith that was to come would be revealed. So the law was our guardian until Christ came that we might be justified by faith. Now that this faith has come, we are no longer under a guardian.
Ephesians 2:14-15 NIV For he himself is our peace, who has made the two groups one and has destroyed the barrier, the dividing wall of hostility, by setting aside in his flesh the law with its commands and regulations. His purpose was to create in himself one new humanity out of the two, thus making peace,
Christians are under the Law of Christ, not the Old Testament Law
Galatians 6:2 NIV Carry each other’s burdens, and in this way you will fulfill the law of Christ.
The law of Christ a summary of Jesus’ response to a question about the greatest Commandment.
Matthew 22:34-40 NIV Hearing that Jesus had silenced the Sadducees, the Pharisees got together. One of them, an expert in the law, tested him with this question: “Teacher, which is the greatest commandment in the Law?” Jesus replied: “ ‘Love the Lord your God with all your heart and with all your soul and with all your mind.’ This is the first and greatest commandment. And the second is like it: ‘Love your neighbor as yourself.’ All the Law and the Prophets hang on these two commandments.”
This doesn’t mean the Old Testament law is irrelevant today. Many of the commands in the Old Testament law fall into the categories of “loving God” and “loving your neighbor.” The Old Testament law can be a good guidepost for knowing how to love God and knowing what goes into loving your neighbor.
The Ten Commandments were essentially a summary of the entire Old Testament law. Nine of the Ten Commandments are clearly repeated in the New Testament (all except the command to observe the Sabbath day). If we are loving God, we will not be worshipping false gods or bowing down before idols. If we are loving our neighbors, we will not be murdering them, lying to them, committing adultery against them, or coveting what belongs to them. The purpose of the Old Testament law is to convict people of our inability to keep the law and point us to our need for Jesus Christ as Savior.
Romans 7:7-12 NIV What shall we say, then? Is the law sinful? Certainly not! Nevertheless, I would not have known what sin was had it not been for the law. For I would not have known what coveting really was if the law had not said, “You shall not covet.” But sin, seizing the opportunity afforded by the commandment, produced in me every kind of coveting. For apart from the law, sin was dead. Once I was alive apart from the law; but when the commandment came, sin sprang to life and I died. I found that the very commandment that was intended to bring life actually brought death. For sin, seizing the opportunity afforded by the commandment, deceived me, and through the commandment put me to death. So then, the law is holy, and the commandment is holy, righteous and good.
Galatians 3:23-24 NIV Before the coming of this faith, we were held in custody under the law, locked up until the faith that was to come would be revealed. So the law was our guardian until Christ came that we might be justified by faith.
While we will never keep God’s commandments or be righteous before Him by our own efforts, Christ did. It is His sacrificial death on the cross that causes our sins to be imputed to Him and His righteousness imputed to us.
Romans 3:21-22a NIV But now apart from the law the righteousness of God has been made known, to which the Law and the Prophets testify. This righteousness is given through faith in Jesus Christ to all who believe.
Here's the problem;
Romans 7:14-20, 25 NIV We know that the law is spiritual; but I am unspiritual, sold as a slave to sin. I do not understand what I do. For what I want to do I do not do, but what I hate I do. And if I do what I do not want to do, I agree that the law is good. As it is, it is no longer I myself who do it, but it is sin living in me. For I know that good itself does not dwell in me, that is, in my sinful nature. For I have the desire to do what is good, but I cannot carry it out. For I do not do the good I want to do, but the evil I do not want to do—this I keep on doing. Now if I do what I do not want to do, it is no longer I who do it, but it is sin living in me that does it. Thanks be to God, who delivers me through Jesus Christ our Lord! So then, I myself in my mind am a slave to God’s law, but in my sinful nature a slave to the law of sin.
Here's the solution;
Romans 10:9-13 NIV If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved. As Scripture says, “Anyone who believes in him will never be put to shame.” For there is no difference between Jew and Gentile—the same Lord is Lord of all and richly blesses all who call on him, for, “Everyone who calls on the name of the Lord will be saved.”
Salvation is not by the Law
The gospel message is that we can receive forgiveness of sins through faith in the sacrifice of Christ. It was Jesus who kept of the law perfectly and never sinned sacrificed His life and died for our salvation.
1 Peter 2:21-22 NIV To this you were called, because Christ suffered for you, leaving you an example, that you should follow in his steps. “He committed no sin, and no deceit was found in his mouth.”
Christians have "died with Christ"
Romans 6:4 NIV We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life.
That means that they have also died to the law
Romans 7:4-6 NIV So, my brothers and sisters, you also died to the law through the body of Christ, that you might belong to another, to him who was raised from the dead, in order that we might bear fruit for God. For when we were in the realm of the flesh, the sinful passions aroused by the law were at work in us, so that we bore fruit for death. But now, by dying to what once bound us, we have been released from the law so that we serve in the new way of the Spirit, and not in the old way of the written code.
Therefore, Christians are not obligated to keep the law in order to be saved. But, when we love God, love our neighbor, and love one another, it's love that fulfills the law.
