Wasn't Torah just for the Jews?
No! There were no "Jews" until Jacob begat the Tribe of Judah (Judah - Genesis 29:35; Matthew 1:1-2)! "The Jews" has simply become a blanket description for all Israelites - but in actuality, only someone born into the Tribe of Judah can claim they are Jews. The Tanach (OT) shows that His Chosen were called Hebrews (see Genesis 12 through 14). Abraham, our first patriarch, was BORN A GENTILE in Ur of the Chaldees - Babylon - and he BECAME a Hebrew, which means "to cross over." This happened when he physically left Babylon and spiritually became a child of YHWH, doing YHWH's will.
So, logically, we can come to the conclusion that back when YHWH created the world and made the Seventh Day holy (Genesis 2:2-3), He wasn't talking to "the Jews"! Adam and Eve, to whom He gave His first rules weren't Jews, and neither were Cain and Abel who offered the first sin sacrifices (Genesis 4:3-5). And Noah, who also was not a Jew, knew the difference between "clean and unclean" animals (Genesis 7:2-3)....Yet EVERYONE was Torah observant.
This totally negates the Christian claim that they don't have to obey God's Law! Anyone who believes in the God of Abraham, Isaac and Jacob is to be Torah observant, and God even said so FOUR TIMES IN A ROW in Numbers 15:13-16! And this was reiterated in Jeremiah 31:32 when YHWH made His New Covenant with the Houses of Israel and Judah - both of whom were Torah observant.
