YES, The Ten Commandments still go for us today! anything the Lord modified He informed us of it. Any changes that exist are due to blood sacrifices of ram, lamb, bullock and etc. Jesus is now the Lamb Slain as the Blood sacrifice for our sins.
We shouldn't be controversial on this topic but have faith that through all the generations of faithful leaders of God's People both Gentile and Jew, the Lord would have very emphasized the Sabbath observance to His Gentile Pastors and Prophets on such an important topic, however, if a leader or believer is close-minded to a Truth, the Lord is patient to allow them to open their heart to be able to receive revelation knowledge, or a doctrinal truth, for without faith/belief it is impossible to please God. God will reveal a thing or open understanding when our heart is ready to receive and believe it. Let's not wrestle with God's Word and only Believe.
The Sabbath is still holy, Observe it if you will but it is written to keep ALL of it when we do. Once I spoke with a 7th day Adventist, who drove over 4 miles to her church on Saturday when travelling more than a mile on Sabbath is forbidden. Exodus-16-29/ In Exodus 31 the scripture emphatically says Israel is to forever observe Sabbath perpetually. Ex. 31
do His commands as proof of our Love to God, not as a way to earn our
way into His heart or Heaven. Abraham showed his love and
commitment to God by offering Isaac, we must be willing to offer our
all to God too, sacrifice the pleasures of sin, not holding onto anything more than the Lord. First and foremost is to Love the
Lord thy God with all our heart, mind, body, and soul.
Although the below scripture says God brought them out of Egypt, well...Israel is still God's chosen people and If we serve a Jewish Lord, we honor/respect the same commands as
He gave them/us, even when the death angel passed through Egypt and the lamb's blood was placed on the doorposts of the obedient to save the firstborn, the servants and handmaidens within the home of other races were also spared if firstborn. The Lord has one Word to All who Love and Follow Him. Holiness hasn't changed, Sin cannot be modernized, changed or redefined, What God calls Righteousness in the Old Testament is still Righteousness today.
