Paul spoke about multiple categories of law other than the Law of God, such as the law of sin and works of the law, so it is important to correctly identify which law he is speaking about. For example, in Romans 7:25-8:2, Paul contrasted the Law of God with the law of sin and contrasted the Law of the Spirit with the law of sin and death. In Acts 5:32, the Spirit has been given to those who obey God, so obedience to God is part of the way to receive the Spirit, however, Galatians 3:1-2 denies that "works of the law" are part of the way to receive the Spirit, therefore that phrase does not refer to obedience to God. In Romans 3:27-31, Paul contrasted a law of works with a law of faith, so works of the law are of works while he said that our faith upholds God's law, so it is of faith, and a law that our faith upholds can't be referring to the same thing as the works of the law that are not of faith in Galatians 3:10-12.Gal 3: 10 For as many as are of the works of the law are under the curse; for it is written, “Cursed is everyone who does not continue in all things which are written in the book of the law, to do them.”
God is trustworthy, therefore His instructions are also trustworthy (Psalms 19:7), so the way to rely on God is by obediently relying on His instructions, it is contradictory to think that we should rely on God, but not His instructions, and the position that God's instructions are untrustworthy or not of faith is the position that denies the trustworthiness or faithfulness of God.
According to Deuteronomy 27-28, relying on the Law of God is the way to be blessed while not relying on it is the way to be cursed, so Galatians 3:10 should not be interpreted as quoting from those chapters in order to support a point that is arguing against them by saying that relying on the Law of God is the way to be cursed while not relying on it is the way to avoid being cursed. Rather, it says cursed is everyone who does not continue to obey the Law of God, so the only way to avoid being cursed by it is by continuing to live in obedience to it, so those who rely on works of the law instead of the Book of the Law come under that curse.
In Galatians 3:10-12, Paul connected a quote from Habakkuk 2:4 that the righteous shall live by faith with a quote from Leviticus 18:5 that the one who obeys the Law of God will live by it, so the righteous who are living by faith are the same as those who aer living in obedience to the Law of God. Furthermore, the context of Habakkuk 2 contrasts the righteous who are living by faith with those who are not living in obedience to God's law, and in Isaiah 51:7, the righteous are those on whose heart is the Law of God, so the righteous living by faith does not refer to a manner of living that is not in obedience to it.
In Galatians 3:16-19, a new covenant does not nullify the promise of a covenant that has already been ratified, so it is also true that the New Covenant does not abolish our need to obey the Law of God in accordance with the promise. In Matthew 7:23, Jesus said that he would tell those who are workers of lawlessness to depart from him because he never knew them, so the Law of God brings us to Christ because it was given to teach us how to know him, but does not lead us to him so that we can then reject everything he taught and go back to being workers of lawlessness. Someone who disregarded everything that their tutor taught them after they left would be missing the whole point of a tutor. Moreover, in Galatians 3:26-29, every aspect of being children of God, in Christ, through faith, and children of Abraham and heirs to the promise is directly connected with living in obedience to the Law of God (1 John 3:4-10, 1 John 2:6, Matthew 23:23, John 8:39).19 What purpose then does the law serve? It was added because of transgressions, till the Seed should come to whom the promise was made; and it was appointed through angels by the hand of a mediator. 20 Now a mediator does not mediate for one only, but God is one.
21 Is the law then against the promises of God? Certainly not! For if there had been a law given which could have given life, truly righteousness would have been by the law. 22 But the Scripture has confined all under sin, that the promise by faith in Jesus Christ might be given to those who believe. 23 But before faith came, we were kept under guard by the law, [f]kept for the faith which would afterward be revealed. 24 Therefore the law was our [g]tutor to bring us to Christ, that we might be justified by faith. 25 But after faith has come, we are no longer under a tutor.
It is not what the bible says.
In Romans 7, Paul said that the Law of God is holy, righteous, and good and that he wanted to do good, but contrasted that with the law of sin that was working within his members to cause him not to do the good that he wanted to do. In Romans 7:7, the Law of God is not sinful, but is how we know what sin is, and when our sin is revealed, then it leads us to repent and causes sin to decrease, however the law of sin stirs up sinful passions in order to bear fruit unto death, so it is sinful and causes sin to increase. So verses that refer to a law that is sinful, that causes sin to increase, or that hinders us from obeying the Law of God should be interpreted as referring to the law of sin rather than to the Law of God, such as Romans 5:20, Romans 6:14, Galatians 2:19, Galatians 5:16-18, and 1 Corinthians 15:56.Paul said the law caused sin to increase. Not decrease.
It is contradictory to think that we are looking to self by relying on God's instructions instead of looking to God. The way to turn to God to love as He loved is not by refusing to follow His instructions, but just the opposite.those who look to the law to see how to behave are looking to self. Turn from that. Turn to God and love as he loved, and you will fulfill the law. These are jesus words.
The position that we should obey the greatest two commandments is also the position that we should obey all of the commandments that hang on them, for example, it would be contradictory for someone to think that we should love God and our neighbor, but that we don't need to refrain from commit idolatry, adultery, theft, murder, rape, kidnapping, favoritism, and so forth for the rest of the Law of God.Matt 22:
34 But when the Pharisees heard that He had silenced the Sadducees, they gathered together. 35 Then one of them, a lawyer, asked Him a question, testing Him, and saying, 36 “Teacher, which is the great commandment in the law?”
37 Jesus said to him, “‘You shall love the Lord your God with all your heart, with all your soul, and with all your mind.’ 38 This is the first and great commandment. 39 And the second is like it: ‘You shall love your neighbor as yourself.’ 40 On these two commandments hang all the Law and the Prophets.”
