Brothers and Sisters, Paul assumes the listener knows what is written elsewhere and uses summary words like "the law" where the word has already been expanded elsewhere. When Paul uses the word law, unqualified, he is referring to the law of Judaism Jesus has freed us from as accepted in the Jerusalem council expressed by James. The Jerusalem council did not abandon Moses and everything that came before Moses when it provided a seed list to add to, allowing the adoption of Moses and everything before Moses by the gentiles who were turning to God free of the added human traditions of Judaism that Jesus was against in the following passage.
“What sorrow awaits you teachers of religious law and you Pharisees. Hypocrites! For you shut the door of the Kingdom of Heaven in people’s faces. You won’t go in yourselves, and you don’t let others enter either. “What sorrow awaits you teachers of religious law and you Pharisees. Hypocrites! For you cross land and sea to make one convert, and then you turn that person into twice the child of hell you yourselves are! “Blind guides! What sorrow awaits you! For you say that it means nothing to swear ‘by God’s Temple,’ but that it is binding to swear ‘by the gold in the Temple.’ Blind fools! Which is more important—the gold or the Temple that makes the gold sacred? And you say that to swear ‘by the altar’ is not binding, but to swear ‘by the gifts on the altar’ is binding. How blind! For which is more important—the gift on the altar or the altar that makes the gift sacred? When you swear ‘by the altar,’ you are swearing by it and by everything on it. And when you swear ‘by the Temple,’ you are swearing by it and by God, who lives in it. And when you swear ‘by heaven,’ you are swearing by the throne of God and by God, who sits on the throne. (Matthew 23:13-22 NLT)
James was not limiting what we need to obey, he was giving us permission to adopt Moses without forcing the human traditions of Judaism on us Gentiles, as we turn to God by giving us a seed, a beginning to add to. James saw us as the fulfillment of the prophecy where God would "restore the fallen house of David" as we listened to Moses every Sabbath. What that means is the equivalent of continuing Judaism without human traditions. The human traditions in Judaism led to death by sabotaging God's Ten Commandments so as not to take away sin that would otherwise have been taken away if they had done what God asked, instead of replacing what God asked with their own rules, in their "human effort" to help them obey the law by sabotaging the law so as not to take away sin, which made the law easier to bear. For example, in order not to use God's name in vain, Judaism added the human rule not to pronounce God's name to help obey God's law by preventing them from having to learn not to misuse His name. Judaism managed to bypass the active part of taking away their sin by replacing God's law with their own rule not to utter God's name at all.
When they had finished, James stood and said, “Brothers, listen to me. Peter has told you about the time God first visited the Gentiles to take from them a people for himself. And this conversion of Gentiles is exactly what the prophets predicted. As it is written: ‘Afterward I will return and restore the fallen house of David. I will rebuild its ruins and restore it, so that the rest of humanity might seek the LORD, including the Gentiles—all those I have called to be mine. The LORD has spoken—he who made these things known so long ago.’ “And so my judgment is that we should not make it difficult for the Gentiles who are turning to God. Instead, we should write and tell them to abstain from eating food offered to idols, from sexual immorality, from eating the meat of strangled animals, and from consuming blood. For these laws of Moses has been preached in Jewish synagogues in every city on every Sabbath for many generations.” (Acts 15:13-21 NLT fixed)
Paul is against the "human effort" in Judaism, as in the story of Hagar, to sabotage the law of God to not remove sin, sin that the law of God is meant to remove. For example, Judaism obeyed not to misuse God's name by not pronouncing His name at all, when their human rule stops the purpose of God's Commandment to separate the sin of misusing His name from our character thanks to the practice gained by the cycle of forgiveness made clear in the animal sacrifices. God's Commandment is meant to separate that sin from our character, that Judaism prevented with their rule that leads to death, because they are preventing God's laws from separating sin from our character.
Well then, since God’s grace has set us free from the law (of Judaism), does that mean we can go on sinning (lawlessness)? Of course not (don't misunderstand God's grace)! Don’t you realize that you become the slave of whatever you choose to obey (sin or God)? You can be a slave to sin (lawlessness), which leads to death (like Judaism's example of sabotaging God's Ten Commandments to not remove sin), or you can choose to obey God (Eleven Commandments), which leads to righteous living (freedom from sin). Thank God (Jesus's many forgivenesses as our High Priest allowing us to grow in obedience through practice of the Eleven Commandments)! Once you were slaves of sin (lawlessness), but now you wholeheartedly obey this teaching we have given you (Eleven Commandments). Now you are free from your slavery to sin (when you obey God's Eleven Commandments), and you have become slaves to righteous living (obeying the Eleven Commandments). (Romans 6:15-18 NLT)
The sabotage of God's law found in Judaism, like the sabotage in the "human effort" in the story of Hagar, is expressed in the following passage.
Tell me, you who want to live under the law (the rules of Judaism that does not remove sin), do you know what the law actually says? (The law says what is sin) The Scriptures say that Abraham had two sons, one from his slave wife and one from his freeborn wife. The son of the slave wife was born in a human attempt to bring about the fulfillment of God’s promise (the promise to remove sin from our character). But the son of the freeborn wife was born as God’s own fulfillment of his promise. These two women serve as an illustration of God’s two covenants. The first woman, Hagar, represents Mount Sinai where people received the law that enslaved them (Judaism is enslaved in sin because they sabotaged God's law to not remove sin). And now Jerusalem is just like Mount Sinai in Arabia, because she and her children live in slavery (slavery to sin) to the law (added by the translators, not found in the original). But the other woman, Sarah, represents the heavenly Jerusalem. She is the free woman (free from sin), and she is our mother. As Isaiah said, “Rejoice, O childless woman, you who have never given birth! Break into a joyful shout, you who have never been in labor! For the desolate woman now has more children than the woman who lives with her husband!” And you, dear brothers and sisters, are children of the promise (the promise to remove sin from our character), just like Isaac. But you are now being persecuted by those who want you to keep the law (the rules of Judaism that does not remove sin), just as Ishmael, the child born by human effort, persecuted Isaac, the child born by the power of the Spirit. But what do the Scriptures say about that? “Get rid of the slave and her son, for the son of the slave woman will not share the inheritance with the free woman’s son.” So, dear brothers and sisters, we are not children of the slave woman; we are children of the free woman. (Galatians 4:21-31 NLT fixed)
Hagar's son to Abraham came from the human will and not from God's will to give Abraham a son through Hagar. Hagar is not the will of God expressed on Mount Sinai but the "human attempt" to fulfill the will of God expressed on Mount Sinai. Therefore, it is not God's laws that are tied to Hagar, but human rules found in Judaism that come from sinful "blind guides" to use laws to accomplish God's will expressed on Mount Sinai, that Jesus says in the following passage: "shut the door of the Kingdom of heaven in people's faces". It is not God's laws expressed on Mount Sinai that "shut the door of the kingdom of heaven in people's faces", it is Judaism's human replacement rules for God's laws that "shut the door of the Kingdom of heaven in people's faces".
“What sorrow awaits you teachers of religious law and you Pharisees. Hypocrites! For you shut the door of the Kingdom of Heaven in people’s faces. You won’t go in yourselves, and you don’t let others enter either. “What sorrow awaits you teachers of religious law and you Pharisees. Hypocrites! For you cross land and sea to make one convert, and then you turn that person into twice the child of hell you yourselves are! “Blind guides! What sorrow awaits you! For you say that it means nothing to swear ‘by God’s Temple,’ but that it is binding to swear ‘by the gold in the Temple.’ Blind fools! Which is more important—the gold or the Temple that makes the gold sacred? And you say that to swear ‘by the altar’ is not binding, but to swear ‘by the gifts on the altar’ is binding. How blind! For which is more important—the gift on the altar or the altar that makes the gift sacred? When you swear ‘by the altar,’ you are swearing by it and by everything on it. And when you swear ‘by the Temple,’ you are swearing by it and by God, who lives in it. And when you swear ‘by heaven,’ you are swearing by the throne of God and by God, who sits on the throne. (Matthew 23:13-22 NLT)
