God always works through mediators. He used Israel to reveal Himself to the world and bring salvation to the world.
Isaiah 49:1-6 Listen to me, you islands; hear this, you distant nations: Before I was born the Lord called me; from my mother’s womb he has spoken my name. He made my mouth like a sharpened sword,in the shadow of his hand he hid me; he made me into a polished arrow and concealed me in his quiver. He said to me, “You are my servant, Israel, in whom I will display my splendor.” But I said, “I have labored in vain; I have spent my strength for nothing at all. Yet what is due me is in the Lord’s hand, and my reward is with my God.” And now the Lord says,he who formed me in the womb to be his servant to bring Jacob back to him and gather Israel to himself, for I am honored in the eyes of the Lord and my God has been my strength, he says: “It is too small a thing for you to be my servant to restore the tribes of Jacob and bring back those of Israel I have kept. I will also make you a light for the Gentiles, that my salvation may reach to the ends of the earth.”
Any Law God gave to Israel He gave through Israel to the whole world.
Exodus 12:49 "One law shall be for the native-born and for the foreigner who dwells among you."
Leviticus 24:22 "You shall have the same law for the stranger and for one from your own country; for I am the Lord your God.’”
The Law, including the sacredness of the seventh day Sabbath, was given to all mankind, including the Gentiles and even the animals as well.
Isaiah 56:1-8 This is what the Lord says: "Be just and fair to all. Do what is right and good, for I am coming soon to rescue you and to display my righteousness among you. Blessed are all those who are careful to do this. Blessed are those who honor my Sabbath day of rest and keep themselves from doing wrong. "Don't let Gentiles who commit themselves to the Lord say, "The Lord will never let me be part of his people." And don't let the eunuchs say, "I'm a dried-up tree with no children and no future." For this is what the Lord says: I will bless those eunuchs who keep my Sabbath day holy and who choose to do what pleases me and commit their lives to me. I will give them within the walls of my house a memorial and a name far greater than sons and daughters could give. For the name I give them is an everlasting one. It will never disappear! "I will also bless the Gentile who commit themselves to the Lord, who serve him and love his name, who worship him and do not desecrate the Sabbath day of rest, and who hold fast to my covenant. I will bring them to my holy mountain of Jerusalem and will fill them with joy in my house of prayer. I will accept their burnt offerings and sacrifices, because my house will be called a house of prayer for all nations. For the Sovereign Lord, who brings back the outcasts of Israel, says: I will bring others, too, besides my people Israel."
