If you love the Lord, you love the day He has given you to keep and 'call the Sabbath a delight, the holy day of the LORD honourable, and shall honour Him, not going your own ways, nor finding your own pleasure, nor speaking your own words. Then you shall delight yourself in the LORD; and [God] will cause you to ride on the high hills of the earth' (Isaiah 58:13-14). The fourth commandment is a moral law, which is why it is found with the other moral laws.
This was for the people God brought from Egypt, not you. And Jeremiah says: ““Indeed, a time is coming,” says the Lord, “when I will make a new covenant with the people of Israel and Judah.It will not be like the old covenant that I made with their ancestors when I delivered them from Egypt. For they violated that covenant, even though I was like a faithful husband to them,” says the Lord.” (Jeremiah 31:31–32)
And the Ten Commandments ARE the Old Covenant the New Covenant replaced. The TEN Commandments ARE the Old Covenant the New Covenant replaced them.
In
Exodus 34:28 we read: “And He (God) wrote upon the tables the words of the covenant, the Ten Commandments.”
Deuteronomy 4:13: “And He declared unto you His covenant, which He commanded you to perform, even the Ten Commandments.”
Deuteronomy 9:9: “When I was gone up into the mount to receive the tables of stone, even the tables of the covenant.”
Deuteronomy 9:15: “So I turned and came down from the mount . . . and the two tables of the covenant were in my two hands.”
And so on...................
We only use the Ten Commandments to convict sinners in evangelism, and to help train new converts in repentance. If you walk in the Spirit, you will keep them with a proper motive - love, by keeping the Two Great Commandments.
