You've got that backwards. Christ says "all the law and prophets hang upon these two commandments" (Mat 22:40) Christ does not say these two commandments come from the 10 (which is found nowhere in scripture) but rather the 10 (and the rest of the law and prophets) come from these 2 laws.
This is what Christ said:
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.”
Where does the Second Greatest commandment come from on how to love thy neighbor? Right from the Ten Commandments that deal with the commandments on how to love mankind.
Rom 13:9 9 For the commandments, “You shall not commit adultery,” “You shall not murder,” “You shall not steal,” [
a]“You shall not bear false witness,” “You shall not covet,” and if
there is any other commandment,
are all summed up in this
saying, namely,
“You shall love your neighbor as yourself.”
Where does the Greatest Commandment come from to love God with all thy heart and soul? From this same unit of Ten as shown in Deut 5 (quoting from Exo 20:1-17_ and Deut 6, what Jesus was quoting from.
Love to God, love to man hang all the law and Prophets (God's Word) God never left undefined how to love Him or how to love our neighbor 1 John 5:2-3 but sadly most rely on their own version of love Jer 17:9 instead of allow God to direct our paths in all ways including how to love Exo 20:6 Mat 14:15
No wonder why the wisest man said this:
Ecc 12:13
Let us hear the conclusion of the whole matter:
Fear God and keep His commandments,
For this is man’s all.
14 For God will bring every work into judgment,
Including every secret thing,
Whether good or evil.
What Christ reveals is a universal (unchanging) construct that covenant law (temporary) is based on. With regards to the sabbath and questions regarding how in practice does Christ law look like Christ answers this specifically affirming that doing good (goodness that is synonymous with Christ's law) is lawful practice on the Sabbath even if it means the act of doing good involves work it still is lawful practice.
Since our rest action on the Sabbath cannot fulfill the sabbath because we cannot complete the work why not do an action that can fulfill the Sabbath? "For the entire law is fulfilled in keeping this one command: “Love your neighbor as yourself." (Gal 5:14). This certainly covers the 4th commandment.
Ultimately creation is a salvation metaphor and the 7th day is a complete work in us that ushers is God's rest and we are called holy which is the process of scarification. We are the new creation and in the new creation we keep the 7th day holy by keeping ourselves holy.
I am going to listen to what God said. Exo 20:6 John 14:15 Isa 56:1-2 1 John 5:3 Mat 15:3-14 Mark 7:7-13 Mat 5:19-30 Luke 4:16 1 John 2:6 John 15:10 because our ideas, thoughts, wants and desires are important to us, but its not the same as what God says.
For example, there is no Scripture that says "Since our rest action on the Sabbath cannot fulfill the sabbath because we cannot complete the work why not do an action that can fulfill the Sabbath? " There is nothing in the Sabbath commandment about not keeping because we can't complete the work. The God I serve gives us the power to keep His commandments, just as He said through Him John 14:15-18. God said
not to work on the seventh day Exo 20:8-11 so we can keep the Sabbath day holy Exo 20:6 placing our minds on Jesus doing this to honor and worship Him. Isa 58:13 so of course it can be kept, just the way God said it could. Its a matter of willingness and decision.
There is nothing that says
" We are the new creation and in the new creation we keep the 7th day holy by keeping ourselves holy." Man can't make ourselves holy, nor can we make a day holy, only God can do that. God from the beginning made the seventh day Sabbath holy, He blessed and sanctified for holy use and commanded us to keep the seventh day Sabbath holy Exo 20:8-11 by putting aside all secular activities and focus on God for one day on the day He set aside to do so. Isa 58:13 So God can bless Isa 56:1-2 and sanctify us Eze 20:12, because man can't sanctify ourselves Isa 66:17 , which we try to do when they create our own version of how to keep God's Sabbath or lay it aside saying its not for me Mark 7:7-13 Mat 15:3-14. something we were warned would happen in the last days Acts 20:30. Its best just to stick with what He said, just the way He said it and not try to speak for Him, as He doesn't need our help. Probably why Jesus said, man shall not live by bread alone but by every word that proceeds out of the mouth of God Mat 4:4, quoting from the OT, because its best to let God be God and we be His humble servants living by His Word, not what sounds good to our itching ears.
