The ONLY "law of GOD" (meaning the only "DIVINE" spiritual law) that ever existed before the crucifixion was the 10 Commandments.....MOSES added many "ordinances"/rules of worship (wear this robe, wear your hair like this, etc.....called "Mosaic law"). Technically, Mosaic law IS NOT a "LAW OF GOD" (the Jews felt that it was "divine" law,...."All who came before me are thieves and robbers", John 10).
Even though the law of Moses is not divine law, on the cross, Jesus abolished both.......God made it very clear in scripture.....
"by abolishing in his flesh the law of commandments and ordinances".
The modern worshiper ("True worshiper", John 4:23) should be concerned with NEITHER Mosaic law nor the 10 commandments (we are NOT Jews).
The 10 commandments were the list of requirements that must be fulfilled in order to be PERFECT (only GOD can be perfect). They were simply meant to show the Jews that they need the promised Messiah, but many never caught on (some did).
The only law that we are to observe is the law of liberty (it is the PERFECT LAW).....
"So speak and so act as those who are to be judged under the law of liberty".
......the law of liberty is for the believers who will look into the PERFECT LAW....(will you?...your choice).
James 1:25 "but if you look into the perfect law, the law of liberty...".
All throughout history, believers have not been taught to "look into" the perfect law (argue if you will, it's true). Many, many "truths" have never been taught (complain and stomp your feet all you want, we have been taught WRONG). The only doctrine we should be concerned with is the "DOCTRINE OF CHRIST" (Christ and Him crucified, the final/everlasting 'sin sacrifice').
2 John 1:9
"Any one who goes ahead and does not abide in the doctrine of Christ does not have God".
The "WORD OF GOD" (JESUS is "the Word", not scripture) became FLESH and hung on the cross in order to END "sin". Jesus came to earth at the end of the age of time to be the FINAL (once for all) sacrifice (offering) for transgressions/"sin" of the 10 commandments......
"he has appeared once for all at the end of the age to put away sin".
....Jesus came in the "fulness of time" (the completion and end of time) and ushered in the age of ETERNITY (The Lord's "day" is the ETERNAL SABBATH)....
Mark 10:30 and Luke 18:30
"and in the age to come eternal life".
The Jews used to perform rituals in order as gifts to God and present offerings and sacrifices to God in order to be "purified" of "sin", but they had to do this repeatedly every year because that "purification" was not TRULY SUFFICIENT for God. So the Father sent Jesus to be the FINAL sin sacrifice (the lamb of GOD is the ONLY sufficient sacrifice and is EVERLASTING/FINAL).
God has "PUT AWAY" sin ("sin" has no more divine meaning....IN CHRIST)....The "law of COMMANDMENTS" (law of "SIN" and death) has been ABOLISHED/destroyed for the believer in Christ.....the word "sin" today is only loosely used to mean "WRONGDOING" but has no more divine meaning at all. The Jews did not have the final sin sacrifice available to them (WE do), so God said that they shall never enter His rest....
"For we who have believed enter that rest, as he has said, "As I swore in my wrath, 'They shall never enter my rest,'" although his works were finished from the foundation of the world".
"they would no longer have any consciousness of sin".
