This same thought applies to the Law of God,
The Law of God is for all to keep, and was clearly in effect in the Garden of Eden.
Abraham walked with God and was taught of God as it was intended from the beginning.
The law of Moses is a complete law that can not be dissected into which we will and will not keep. The law of Moses has vanished away.
The law of God that was, is and forever will be,is intact and is what remains.
The Law of God is seen in the 10 commandments but is certainly not limited to the 10 commandments.
God's Law is also what He tells you to do directly, such as -
"Get out of your country, From your family And from your father's house, To a land that I will show you.
or -
"Arise and go to the street called Straight,
or
Go to the house of Cornelius...
or even a more infamous one -
"Of every tree of the garden you may freely eat; but of the tree of the knowledge of good and evil you shall not eat,
These commandments are far more important and weighty than, keep the sabbath.
For some reason though, I don't hear to much about these commandments from those who seem to think the law of Moses is to be kept today.
I can go on about the Sabbath and what it does for us as well as many other laws, but it's pointless if someone is convinced that they are not obligated to keep the Law.
The Sabbath is for man to rest. Man needs a day of rest.
However, the Sabbath that was required in the law of Moses, with all the stipulations such as do not kindle a fire, is obsolete and has vanished away.
