Mostly, yes. The Torah says if you're son of Israel, you must do all of these things, because God has set you apart to Himself. It also says, everyone who dwells in the land must NOT practice sexual immorality, idolatry, or eating blood because these things are an abomination for anyone to do.
And it teaches by example how the life of a person who is pleasing to God looks.
St Paul says, ok - yes, Jesus of Nazareth is the Messiah, and is the Word of Yahweh, the God of the Jews. Yes, the Jews worship Yahweh and by their law / custom (Torah) they have to live a certain way. But the great mystery is that people of the other nations - non-Jews - can come to worship the God of the Jews through Jesus also. Not only that, but they can become heirs to all the promises made to the Jews through Abraham because Jesus inherits all of these promises as the firstborn! And, the kicker, they do NOT have to become Jews to inherit these promises. They have to be faithful to the heir, and He will distribute the inheritance to all the faithful: Jew or non-Jew, no partiality.
To the Jews, he says - y'all need to open your eyes to the fact that keeping the Torah is not and has never been what saves you. Being faithful to Yahweh - which means Jesus the Messiah - saves you. For sons of Israel that includes keeping the Torah, but keeping the commandments is not enough. Keeping them in an external way but not with the heart is not faithfulness. If you keep the Torah outwardly but do not love, show mercy, defend the orphan and the widow, do not have humility, you have not kept the Torah inwardly, and are not pleasing to God. And rejection of the Messiah means you are unfaithful no matter what you do with regard to the Torah. So the same thing that saves the non-Jew, faithfulness to the Messiah, is what saves the Jew.
To both he says: being faithful to God is what makes you pleasing to God (justifies you, tsedaqah in Hebrew). And if you are faithful to the Messiah the Spirit of God will dwell in you, and you will keep the whole Torah whether you are a Jew or not! Because you will love God and love others, and these fulfill the whole Torah and don't break any of its commandments.
Then he goes on to teach in all of his letters what that life of faithfulness looks like. A life of faithfulness is loving, forgiving, not quarreling, being generous, using your gifts to build up the church, keeping yourself pure, avoiding evil, repenting when you sin, and so on. In other words, faithfulness to the Messiah is good works.
So it it isn't faith plus good works, it is that faith = good works. Good works are the stuff faithfulness is made of.
