There are two different kinds of laws in the Bible, moral laws and Mosaic laws. Mosaic laws are specifically relevant to the theocracy of Israel in the time period between their liberation from Egypt and their rejection of Christ. Moral laws transcend the Mosaic laws because they apply to everyone, not just the nation of Israel.
Look at murder, for example, GOD condemned Cain for murder thousands of years before He ever wrote "Thou shalt not kill" in Exodus chapter 20.
Things like murder, theft, sexual sin (to include homosexuality), idolatry, blasphemy, etc. fall into the category of moral laws and those apply to everyone at every point in history.
Things like animal sacrifices, not wearing mixed fabrics, not getting tattoos, not shaving the sides of your beard, etc., fall into the category of Mosaic laws and only apply to the nation of Israel during a specific historical location and time period.
Moral laws themselves can be summed up in two laws:
1. You shall love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength.
2. You shall love your neighbor as yourself.
In other words, put GOD first, put everyone else in the world second, then put yourself last. Sin and our modern culture tells us to completely turn that list on its head. We are told that we need to look after ourselves first, then worry about others and, if there's time left over, we can worry about GOD.
Is GOD's law impossible to keep? Of course it is, that's the point. The law can only condemn, it can't save anyone. GOD didn't give us His law as a way to say, "Okay, here's a list of everything you need to do to make yourselves righteous." No, He gave us the law to tell us, "This is why you will NEVER be righteous."
The literal translation of the word gospel actually means "good news." Why is Jesus Christ the good news? Because the law was the bad news.
