Keeping the Sabbath is the 4th commandment. If the 4th commandment isn't valid(which it is), then none of the other 9 commandments are valid.
That would mean we don't have to love God, we don't have to honor our parents, we can murder, we can steal, we can lie, we can take God's name in vain, and we can committ all the adultery we want
The 10 Commandments are not multiple choice. What God do you worship if you don't obey the 10 Commandments??
And yes, I do want a farm in Israel
The Ten Commandments are part of the Sinai Covenant. They never applied to anybody but the Hebrews.
There are some of those commandments - notably the commandment against killing and against adultery - that were already revealed before Sinai (the first explicitly to Noah). The other 8, about coveting, or worshiping idols, or keeping the Sabbath, were never given to anybody but the Israelites. The reward for obeying those commandments and the other 603 (or so) given to the Hebrews was a farm in Israel in this life. Not a word about any afterlife, heaven, final judgment.
The Law of Moses, including the Ten Commandments, is completely inapplicable since Christ.
The Commandments of Christ are the only law.
Now, his law reprises some of the Law of Moses, but extends those areas greatly. It also includes a great number of things not in the law of Moses - such as the requirement to forgive men their sins against you in order to be forgiven your sins by the Father. The Temple sacrifices satisfied the old covenant, but they don't satisfy the New. Only what Jesus said satisfies that.
And his Covenant promises life with God in the City of God after the resurrection, but no farm in Israel.
A different covenant, a different law.
There was a period when both laws stood. And in theory the Law of Sinai still stands, but it cannot be followed, as there is no Temple.
Forget Paul, I'm referring strictly to what Jesus himself said, in the Gospels, in Acts and in Revelation. THAT is the Law for us, and that's the ENTIRETY of the law.
Follow the Law of Sinai, and you will put yourself at great effort...to NOT get a farm in Israel, because the WHOLE law has to be followed for the Israelites to get Israel, and it isn't being followed...and indeed, with the destruction of Temple and Priesthood, it CAN'T be followed.
The farm in Israel does not include a room in the City of God afterwards anyway, so you'd do a great deal of effort to follow an old law for another people, and get nothing from it.
Far better to follow what Jesus said, and the Ten Commandments are not part of that. Jesus commanded nothing regarding any Sabbath. Sabbath is a great idea, for human rest, but it has nothing to do with passing final judgment.
Killing and sexual immorality will get you damned. So will lying. Coveting by itself won't, and neither will stealing.
And if you don't forgive others their sins against you, you won't be forgiven your sins. It's quite hard to follow the Law of Jesus - harder than following the 613 mitzvot, actually (assuming the sacrifices could be performed). But if you follow all 613 mitzvot, you're still not entering the City of God at judgment unless you followed Jesus' laws. Conversely, if you followed Jesus' laws and ignored the Law of Moses, you'll get into the City, but if you're a Jew you won't get the farm in Israel.
The Old Covenant was for a piece of land on Earth.
The New Covenant is for an apartment in Heaven.
The two must not be confused.
