Is the Law of Moses Valid for today?

[nleamons]

Are the sacrifices just for the Jewish people or were the sacrifices intended to be for all nations of the Earth? Did not Rahab save the spies and join herself unto Israel? Did not Ruth leave her homeland to live with here Mother-in-law, Naomi? But we know that there is one law unto the homeborn and unto the stranger that sojurneth among thee. Exodus 12:49 and also see Isaiah 56. We see that one, the person has to make a choice to serve God with all they've got. Nor should they be someone; who hears the word, but fails to do it. See James 1;22-24, See Romans 2:12-16 For those of us that believe, the bar is raised higher to maintain a good standard of living as the Bible clearly illustrates.
