I do not follow your reasoning here. Yes, I agree, Jesus adds another commandment (I think the other 10 are retired at the cross, but that is another discussion). But why would it be impossible to "sell all one's possessions and give the money to the poor"?
Brother, happy Sabbath, which starts this Friday March 31, 2023 at 11:57 am EDT! Giving "everything I have to the poor" is not an act of love in the following passage. All the commandments tell us how to love, disqualifying it as the "one thing you haven't done", when Jesus' answer was "the commandments". The "one thing you haven't done" is the newly known additional Eleventh Commandment of the new covenant: where to do "just as I have" is to follow Jesus' example, which was not possible before Jesus.
If I could speak all the languages of earth and of angels, but didn’t love others, I would only be a noisy gong or a clanging cymbal. If I had the gift of prophecy, and if I understood all of God’s secret plans and possessed all knowledge, and if I had such faith that I could move mountains, but didn’t love others, I would be nothing. If I gave everything I have to the poor and even sacrificed my body, I could boast about it; but if I didn’t love others, I would have gained nothing. (1 Corinthians 13:1-3 NLT)
Giving "everything I have to the poor" above is not an act of love for it to qualify as the additional new Eleventh Commandment in the passage below, where the known new Eleventh Commandment is to "follow" the example of Jesus.
Once a religious leader asked Jesus this question: “Good Teacher,
what should I do to inherit eternal life?” “Why do you call me good?” Jesus asked him. “Only God is truly good. But to answer your question,
you know the commandments (entolé): ‘You must not commit adultery. You must not murder. You must not steal. You must not testify falsely. Honor your father and mother.’” The man replied, “
I’ve obeyed all these commandments since I was young.” When Jesus heard his answer, he said, “
There is still one thing you haven’t done. Sell all your possessions and give the money to the poor, and you will have treasure in heaven. Then come, follow me.” (Luke 18:18-22 NLT)
The new Eleventh Commandment above is found in the following passage, where to do "just as I have" is to "follow" His example by keeping a total of Eleven Commandments when Jesus adds one more to the previous Ten Commandments, saying above: "there is still one thing you haven't done".
As soon as Judas left the room, Jesus said, “The time has come for the Son of Man to enter into his glory, and God will be glorified because of him. And since God receives glory because of the Son, he will give his own glory to the Son, and he will do so at once. Dear children, I will be with you only a little longer. And as I told the Jewish leaders, you will search for me, but you can’t come where I am going. So now
I am giving you a new commandment (entolé): Love each other. Just as I have loved you, you should love each other. Your love for one another will prove to the world that you are my disciples.” (John 13:31-35 NLT)
Adding one more Eleventh Commandment to the previous Ten Commandments is consistent with Jesus not changing and bringing us closer to Him.
Jesus Christ is the same yesterday, today, and forever. (Hebrews 13:8 NLT)
First, you obviously assume the very thing you need to make a case for by saying that the new covenant incorporates the 10 commandments? You need to make an actual case for this, not assume it. And that would be a tall order as Paul rather clearly hints at the demise of the Sabbath here:
The evidence that the new Eleventh Commandment was added to the previous Ten Commandments is found in the passage in Luke in the previous answer in this post.
So don’t let anyone condemn you for what you eat or drink, or for not celebrating certain holy days or new moon ceremonies or Sabbaths. 17 For these rules are only shadows of the reality yet to come. And Christ himself is that reality
Hebrews 3 and 4 tells us that the Sabbath in Judaism is wrong outside of Jerusalem, because Joshua did not benefit from the punishment for 40 years in the desert with Manna when God did not allow them to enter His Sabbath by forcing them to keep the seventh day of the week with Manna from morning to morning, like when God rested in Eden. When they arrived in the Promised Land, the Sabbath changed to an earlier time by half a day than the seventh day of the week from evening to evening, because the Sabbath is fixed in the time zone of creation, being the name God gave His rest on that seventh day of creation from morning to morning and not the name of the seventh day of the week as assumed since Joshua.
You then take it upon yourself to edit Paul by taking this phrase: The old written covenant ends in death
...and changing it to this: The old written covenant ends in death (sabotaged by human effort as in the story of Hagar)
On precisely what basis do you know that the reason the old covenant ends in death is that it is "sabotaged by human effort"?
The "human effort" Paul talks about in the following passage, comparing it to the story of Hagar, is humans trying to fulfill God's promise of obedience to the Ten Commandments by replacing them with their own rules that do not remove sin as the actual Ten Commandments do when obeyed. For example, instead of obeying God not to misuse His name, they instead invented their own rule not to pronounce His name at all when their own rule does not help to free them from the sin that the commandment was meat to free them from.
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)
United in our hope for the soon return of Jesus, Jorge
