You are teaching things that are foreign to the word of God and to the plan of God. God used Israel to represent Him to the world. Israel was to be a light to the Gentiles.
Isaiah 42:5-7
Thus says God the Lord,
Who created the heavens and stretched them out,
Who spread forth the earth and that which comes from it,
Who gives breath to the people on it,
And spirit to those who walk on it:
I, the Lord, have called You in righteousness,
And will hold Your hand;
I will keep You and give You as a covenant to the people,
As a light to the Gentiles,
To open blind eyes,
To bring out prisoners from the prison,
Those who sit in darkness from the prison house.
The whole world was to look to Israel to learn the ways of God, this includes honoring the Sabbath.
Isaiah 56:1-8
Be just and fair to all, the Lord God says. Do whats right and good, for I am coming soon to rescue you. Blessed is the man who refuses to work during my Sabbath days of rest, but honors them; and blessed is the man who checks himself from doing wrong. And my blessings are for Gentiles, too, when they accept the Lord; dont let them think that I will make them second-class citizens. And this is for the eunuchs too. They can be as much mine as anyone. For I say this to the eunuchs who keep my Sabbaths holy, who choose the things that please me and obey my laws: I will give themin my house, within my wallsa name far greater than the honor they would receive from having sons and daughters. For the name that I will give them is an everlasting one; it will never disappear. As for the Gentiles, the outsiders who join the people of the Lord and serve him and love his name, who are his servants and dont desecrate the Sabbath, and have accepted his covenant and promises, I will bring them also to my holy mountain of Jerusalem and make them full of joy within my House of Prayer. I will accept their sacrifices and offerings, for my Temple shall be called A House of Prayer for All People! For the Lord God who brings back the outcasts of Israel says: I will bring others, too, besides my people Israel.
Getting more people to believe what you say will still not make it true.
Whether or not someone is able to obey the commandments does not make them void. The standard has been set and God will bring a people up to His standard.
